Glaive Arts are special attacks Gladiolus can perform when directly controlled by the player in Episode Gladiolus DLC, in Chapter 13 Verse 2 in Final Fantasy XV, and during character-swapping in the main game. When killing enemies with Glaive Arts in the main game, the player gains AP, which can be good for AP farming, especially during Timed Quests. Like regular techniques, Gladiolus is invincible while using them (excluding Earthshatter).
Gladiolus's "valor" gauge is built up by chaining regular attacks. Once full, a Glaive Art can be performed. The gauge can be filled multiple times and each full gauge will unlock a more powerful Glaive Art. The gauge will reset after battles end with character swap.
|Earthshatter||When the no bar is filled.||Digs his blade into the ground, creating a small shockwave around himself that damages enemies in its impact zone. Weak and leaves him vulnerable, but a good option against weaker clustered foes.|
|Razor Edge||When the first bar is filled.||A strong, swift, forward swing that covers decent range and knocks enemies down.|
|Tempest||When the second bar is filled.||Three powerful swings, similar to Razor Edge albeit slightly slower.|
|Maelstrom||Unlocked for defeating Enkidu. Usable when the third bar is filled.||Resembles a fusion of Tempest and Dawnhammer. The finishing swing can stagger foes but outright miss nimble ones.|
|Dual Master||Unlocked for defeating Gilgamesh in Episode Gladiolus. Can be used after unleashing Maelstrom.||Unleashes a long series of fierce sword swings that home in on nearby targets, and finishes with a devastating blow that can stagger most foes. Several of the swings can miss against quicker, more agile enemies like Coeurls, instead knocking them away from the combo.|
