== Background ==
The energy sword is the signature weapon of the [[Sangheili]] and has been their chief weapon of nobility since its creation during one of the [[Ages of Discovery]].<ref>'''[http://nikon.bungie.org/misc/ancient_tablets/Tablet4.gif The Covenant Hall of Murals]'''</ref> The Sangheili pride themselves on their skills with the weapon,<ref>'''Halo Graphic Novel''' ''page 12 - 14''</ref> which they regard as holy,<ref name="enyc127">'''[[Halo Encyclopedia (2009 edition)]]''' ''page 127''</ref> and believe that it is better for a Sangheili to fall on his sword to redeem his honor than to die dishonorably.{{Ref/Reuse|enyc127}}<ref>'''Halo: The Cole Protocol''' ''page 53''</ref><ref>'''Halo: The Cole Protocol''' ''page 141''</ref> The Sangheili are very strict on who can be trained in the [[Martial arts|art of swordsmanship]]; in civilian life only [[aristocrat]]s are permitted to wield energy swords.<!-- Note that The Essential Visual Guide confirms that non-aristocratic use of the energy sword is forbidden only within civilian society. This policy is not upheld within the military.-->{{Ref/Reuse|essential}} Sword wielders are not eligible for marriage, though they may breed with any female they choose, married or otherwise, to ensure successful transmission of "swordsman" genes.{{Ref/Reuse|Waypoint}}<ref>'''[[Bestiarum]]''' ''Sangheili section''</ref>

Within the [[Covenant military]], use of the energy sword is not restricted to aristocrats.{{Ref/Reuse|essential}} [[Sangheili Minor]]s are generally not permitted to wield the sword because of the high regard in which it is held,{{Ref/Reuse|enyc127}} though exceptions have been witnessed.<ref>'''Halo Wars''', ''introductory cinematic''</ref><ref name="Package">'''Halo Legends''', ''The Package''</ref> It is unknown whether this extends to [[Sangheili Major|Majors]], as at least one has been witnessed using an energy sword.{{Ref/Reuse|Package}} [[Sangheili Storm|Storm troops]], [[Sangheili Ultra|Ultras]], [[Sangheili Zealot|Zealots]], [[Sangheili General|Generals]], [[Special Operations Sangheili|special operations]], [[Stealth Sangheili|stealth troops]], and [[Sangheili Honor Guardsman|honor guardsmen]] commonly use energy swords.

== Design details ==
The energy sword's design is seen as the logical evolution of an ancient lineage of traditional Sangheili weapons, most notably the twin-scythe and the [[curveblade]];<ref name="H4EVG">'''[[Halo 4: The Essential Visual Guide]]''', ''page 92''</ref>{{Ref/Reuse|Waypoint}} superficially, the twin-scythe's influence on the energy sword's design is unmistakable.<ref>'''Halo Legends''': ''The Package''</ref> Technologically, the energy sword succeeded an older type of Sangheili sword known as the [[burnblade]], which was used in the early years of the Covenant.<ref>''Halo: Broken Circle'', pg. 115</ref> Modern energy swords are manufactured by the [[Merchants of Qikost]], a prominent group of arms makers from one of [[Sanghelios]]' [[Qikost|moons]].{{Ref/Reuse|essential}} The energy sword consists of a curved hilt, which houses an energy storage and generation device, as well as the blade projector; that forms a blade of superheated [[plasma]], stabilized by two small magnetic field generators built into the handle of the weapon—this forms and contains the oval shaped, ionized blades for which the weapon is recognized.{{Ref/Reuse|BungieReach}} The weapon is powered by a small battery that supplies power to the plasma generation device and magnetic field generators which generate and contain the plasma needed to form the blade.<ref name="enyc">'''[[Halo Encyclopedia (2009 edition)]]''' ''page 335''</ref> The battery's energy is reduced for each successful strike. Each strike from the sword will drain the battery by 10% of its maximum energy output. Once the battery power is fully depleted, the sword will deactivate unless recharged. The horizontal hilt forces the wielder to use a punching motion to stab rather than the thrusting motion of most knives and swords.

Mass-produced energy swords feature a roughly W-shaped hilt and have little variation in blade design. Specifically, some models have more rounded blades in lieu of the more common angular style. However, more drastic variations exist. For example, [[Arbiter]] [[Ripa 'Moramee]]'s matching pair of custom-designed<ref>'''Halo: The Essential Visual Guide''', ''page 10''</ref> swords had basket-style hilt guards and radiated a high degree of ionized plasma,<ref>'''Halo Wars'''</ref> whereas most energy swords contain the blades' plasma with greater efficiency. Some Sangheili special forces units wield blood red-colored energy swords which (ironically, despite their color) burn hotter than more common models.{{Ref/Reuse|Waypoint}}<ref name="headH">'''Halo: Evolutions''', ''Headhunters''</ref> Arbiter [[Thel 'Vadam]]'s personal sword, the [[Prophets' Bane]], was pale salmon-colored and had a wider blade compared to mass-produced swords.{{Ref/Reuse|CF}}<ref name="H5G">'''[[Halo 5: Guardians]]'''</ref>

Some energy swords contain a fail-safe mechanism that can permanently disable the weapon if the Sangheili wielding it drops it.<ref>'''Halo: First Strike''' ''page 74''</ref> When dropped, the failsafe engages by deactivating the magnetic field before dispersing the plasma. The plasma then consumes the handle and thus destroys the weapon.<ref>'''Halo: Combat Evolved'''</ref> The fail-safe is included to prevent enemy infantry from acquiring the weapon and using it, and gives insight to Sangheili tactics.

Each energy sword is marked by its creator and first owner, but often their legacy is forgotten.<ref name="LAL">[https://www.halowaypoint.com/en-us/news/canon-fodder-locke-load '''Halo Waypoint''' - ''Canon Fodder: Locke & Load'']</ref>

== Combat application ==
=== Advantages ===
[[File:1221845548 Elites duel wielding energy swords.jpg|thumb|200px|right|[[Rtas 'Vadum]] and [[Kusovai]] dual-wielding energy swords while sparring.]]
The Type-1 energy sword is an extremely devastating and powerful melee weapon when applied during in close-quarters combat. A single strike can even penetrate the energy shield systems, armor, and flesh of a [[SPARTAN programs|Spartan]] or a Sangheili. This is due to the design of the weapon, which utilizes ionized gas rather than traditional shaped, solid matter—because the energy sword lacks any solid material in which to hold, or impale anything, the sword does not cut or carve in the traditional sense, but rather boils anything it comes into contact with.{{Ref/Reuse|enyc}} The Type-1 Energy Weapon's edge is therefore extremely volatile, being able to slice through even the toughest metals like a hot knife through butter, including ODST battle armor and the Titanium-A class plating of UNSC destroyers.<ref name="cole">'''Halo: The Cole Protocol''' ''page 84''</ref><ref>'''Halo: First Strike''', ''page 72''</ref>

Injuries caused by the weapon are often gruesome. Stab wounds by the energy sword are, in most cases, fatal — as the blade passes through the body, the organs and tissues are cauterized by the extreme temperatures produced by the blades.<ref>'''[[Halo: Evolutions]]''' - '''[[Midnight in the Heart of Midlothian]]''', ''page 91''</ref> Body fluids in the area of the stab wound are flash-vaporized upon contact; organs within the area of the stab wounds can suffer life-threatening damage dependent upon which organs are struck. The effects of fluids trapped in organs or arteries and the expansion of heat could lead to ruptures or small explosions, causing additional damage to the victim.

Survival is minimal at best and in the case of non-lethal strikes being administered, proper medical treatment must be applied as soon as possible to ensure permanent survival. Because of the weapon's sheer destructive damage, common forms of fatality to victims include total impalement,<ref>'''[[Halo 4: Forward Unto Dawn]]'''</ref><ref>'''[[Halo Wars]]'''</ref><ref>'''[[Halo: The Cole Protocol]]''', ''page 77''</ref> loss of limbs,<ref>'''[[Halo: The Cole Protocol]]''', ''page 76''</ref> bodies being bisected<ref>'''[[Halo: First Strike]]''', ''page 58''</ref><ref>'''[[Halo: The Fall of Reach]]''' ''page 99''</ref> and decapitation.<ref>'''[[Halo: The Cole Protocol]]''', ''page 79''</ref>

=== Disadvantages ===
The Type-1 Energy Weapon's most glaring downside is that it is purely a close-quarters weapon; any combat engagement outside of the effective range puts the wielder at risk. It is for this reason that the Sangheili approach sword combat on the battlefield in two different ways, by funneling the enemy into close-quarters to allow them to strike, and/ or to apply a form of stealth using both technology and technique. Without these, the user is vulnerable to attack by all forms of ranged attack, especially from sniper-based counterattacks. Infantry with Overshields are also more resistant when facing this weapon as it can take two strikes before the shield system fails and then another for the killing blow.

Furthermore, the Type-1 Energy Weapon is vulnerable to other magnetic fields, as they can block, disrupt, or possibly even alter the functionality of the sword. Two energy blades clashing together create a small disruption of energy as a result of the same type of magnetic fields clashing together; this clash has a slight area of effect damage that can affect the combatants.

As with most other Covenant weapons, the Type-1 Energy Weapon is battery powered, requiring the user to either recharge the weapon (which can never be performed in-game) or discard it when the power is depleted. Although the handle can generally be used as a club, the Energy Sword's combat effectiveness at that point is minimal. The strength and lethality of the sword in the games are compensated for the sake of gameplay.

Last but not least, the Type-1 Energy Weapon can sometimes expose the position of a Sangheili warrior employing active camouflage due to the weapon's energy output.

== Gameplay changes ==
{{Linkbox|gameplay=yes}}
=== Changes from ''Halo: Combat Evolved'' to ''Halo 2'' ===
[[File:Sword.jpg|thumb|right|150px|A blueprint of the energy sword in ''Halo 2''.]]
In ''Halo: Combat Evolved'', the energy sword has a cyan glow, a far less defined edge and makes a dull clunk when striking an object. It is only used by Stealth Sangheili and Zealots. The player cannot wield the energy sword, due to a fail-safe mechanism that vaporizes the weapon when it is not released properly (e.g. being dropped upon death) by the sword-wielder.

In ''Halo 2'', the energy sword is blue with purple undertones, with electrical energy crackling on it when the blade is activated. The white glow seen in ''Halo: Combat Evolved'' is also replaced with a more glass-like transparency. In the campaign, it is only used by higher-ranking Sangheili, such as special operations units, [[Sangheili Ultra|Ultras]] and [[Zealots]], though players can now wield the sword. The sword in campaign has a battery and can only be used effectively against a limited number of enemy forces before the battery runs out. The sword is usable in multiplayer with an infinite battery power. The energy sword has two modes of attacking; a lunge attack and a swing attack.
{{Clear}}

=== Changes from ''Halo 2'' to ''Halo 3'' ===
[[File:ReachSchematic - Sword.png|right|150px|thumb|A blueprint of the energy sword in ''Halo 3''.]]
In ''Halo 3'', the sword has more of a light cyan tinge, similar to its appearance in ''Halo: Combat Evolved'', but still has a tint of purple near the handle. It also has an angle near the handle, whereas in the two previous games it was curved. Players are now able to parry with the Sword. The power exerted by the swords hitting each other will drain both players' shields, but will not kill them unless one makes the fatal blow. The sword's lunge attack has been reduced for balancing purposes. Aside from these changes in design and functionality, the power of the sword remains unchanged. In multiplayer, the sword now has a limited battery supply.
{{Clear}}

=== Changes from ''Halo 3'' to ''Halo: Reach'' ===
In ''Halo: Reach'', the sword is now darker in color. When activated, it is capable of lighting up the surrounding area. When unused, the sword rests differently on the SPARTAN and Sangheili character models. The energy sword appears to have been balanced out compared with its earlier incarnations, having a slightly faster swing than its ''[[Halo 3]]'' incarnation, its lunge attack now does the same damage as a normal swing, the range has been reduced, and can now be blocked by a well-timed normal melee. Players can no longer lunge immediately after a normal swing. The energy sword also has its own assassination animations when used against Elites or Spartans, replacing the Spartan [[combat knife]] and the Sangheili [[energy dagger]]; these assassinations do not deplete the sword's charge, nor do they count toward the weapon spree medals [[Sword Spree]], [[Slice 'N Dice]], or [[Cutting Crew]]. Elites also hold the sword back more than a Spartan when used as an active weapon. When a player is playing as an Elite and uses the Energy Sword as a primary weapon, the camera will lower a bit; this is due to the Elite hunching down. Finally, parrying does slight damage and can kill a player.
{{Clear}}

=== Changes from ''Halo: Reach'' to ''Halo 4'' ===
[[File:EnergySword-HUD.png|right|150px|thumb|HUD icon of the energy sword in ''Halo 4''.]]
Contrary to ''Halo: Reach'', ''Halo 4'' does not feature the possibility to block a sword lunge with a simple melee. Killing an opponent with an energy sword no longer rewards the player with a [[Bone Cracker|Pummel]] medal, it is instead replaced by the [[Sword Kill]] medal. The battery is also drained with every hit, including against walls and floors, so it's far less viable against Hunters and other powerful enemies.
{{Clear}}

=== Changes from ''Halo 4'' to ''Halo 2: Anniversary'' ===
Like the original ''Halo 2'', players cannot parry with the sword. An alternate version of the sword with a red-colored blade, called the ''Infected Energy Sword'', can be used.
* Players can melee with the sword as soon as they swap to it.
* Melee range is drastically increased.
* Unlike its ''Halo 2'' counterpart, its battery can be depleted.
{{Clear}}

=== Changes from ''Halo 2: Anniversary'' to ''Halo 5: Guardians'' ===
The ''Halo 5: Guardians'' sword retains the ability to parry from ''Halo 4''. Unlike in past titles, players can aim with the sword to increase its effective range, and the weapon provides a noticeable speed boost which is enough to make the player visible on the motion sensor while crouching. Three unique versions of the energy sword are available for use: ''[[Ravening Sliver]]'', ''[[Vorpal Talon]]'', and the [[Mythic weapon|mythic]] ''[[Prophets' Bane]]''.

If the energy sword's battery is depleted, the player cannot lunge with the sword.
{{Clear}}

=== Changes from ''Halo 5: Guardians'' to ''Halo Infinite'' ===
* The Energy Sword no longer has the ability to Smart Scope
* Lunges from the Energy Sword depletes ~15% of its battery as opposed to 10% in past games.
* Power ammunition crates and Energy Swords in the battlefield refill its battery without the need to pick up a fresh one.
* The sword is curved again, similar to the ''Halo 2'' and ''Halo 2: Anniversary'' incarnations. The blade is also now a much deeper blue, similar to ''Halo: Reach''’s.
{{Clear}}

==Non-canon and dubious canon appearances==
===Silver Timeline===
{{Main|Silver Timeline}}
Energy swords are used by Covenant Sangheili against humanity.{{Ref/YouTube|Id=HTVOT|5KZ3MKraNKY|Paramount+|Halo The Series (2022) Official Trailer|Y=2022|M=1|D=30}}
== Trivia ==
* The shape of the energy sword is very similar to the real-life combat weapon, the [[Wikipedia:Katara (dagger)|katara]]. It was a South Asian weapon and status symbol, similar to the energy sword's symbolization of status among the Elites.
* The energy sword was originally going to be usable in ''Halo: Combat Evolved'', but was cut when the game became a first-person shooter.<ref>'''[[Halo: Combat Evolved]]''', ''[[E3|E3 2000 Announcement Trailer]]''</ref>
* In ''Halo 2'', the Elites will tell one of them to recover the blade if the player dies while wielding one.
* In the ''Halo 3'' Vidoc [[Et tu Brute?]] there is an unfinished animation depicting a [[Jiralhanae Chieftain]] wielding an energy sword. This is, however, never seen in the hands of Jiralhanae in the final game.
* The ''Fable 2: Limited Edition'' comes with [[Fable:Hal's Sword|"Hal's Sword"]], a crystal blade shaped like an energy sword for in-game use, to coincide with the use of [[Fable:Hal's Armor|"Hal's Armor"]], which resembles [[MJOLNIR]] armor.<ref>[http://www.joystiq.com/2008/10/16/fable-2s-spartan-armor-and-energy-sword-pictured/ '''Joystiq''' - ''Fable 2's Spartan armor and energy sword pictured'']</ref>
* A depleted energy sword hilt can still be used offensively. While the damage varies, it has a higher melee rate than any weapon, allowing the player to barrage an enemy with many hits. Once the hilt is swapped for another weapon, however, it cannot be picked up again and often vanishes entirely.
* In ''Halo 5: Guardians'', the energy sword can turn Spartan charges into one-hit-kills if active. As the Spartan uses the sword to accomplish this, doing so consumes battery.
* The ''Vorpal Talon''{{'}}s ability to maintain the player's motion tracker while scoped is mechanically identical to the Awareness [[support upgrade]] from ''Halo 4''.
*The Energy Sword was found in Bungie's 30th anniversary event as an arc sword Half Truths and a void sword The Other Half in ''Destiny 2''.
*In [[Wikipedia:Konami|Konami]]'s ''[[Wikipedia:Super Bomberman R|Super Bomberman R]]'', the Energy Sword is the weapon used by the [[Arbiter|Arbiter Bomber]].
