Activating Blade Fury causes Rafa to spin his blades, creating a Singularity that draws in all Marked enemies and other nearby enemies while dealing continuous Shock Damage. Whenever this attack kills an enemy, Overdrive grants increased Action Skill Cooldown Rate. |
(Branch 2) |
While Arc-Knives are active, Rafa's Exo-Suit stores all Damage Dealt to him. The Exo-Suit then heats up and constantly deals a small amount of Incendiary Damage to him. Additionally, Rafa's Melee Attacks deal Bonus Incendiary Damage. A portion of all Damage Dealt to Rafa is also dealt to enemies he has Marked. Using Blade Fury causes Rafa to consume all Stored Damage, and deals Bonus Incendiary Damage based on Stored Damage. A portion of all Damage dealt this way is returned to Rafa as Health. |
(Branch 3) |
Whenever Rafa performs a Melee Attack while Arc-Knives are active, fire an Acid STRM Glider at an enemy in his view. Acid STRM Gliders deal Corrosive Splash Damage based on the number of total Marked enemies. Additionally, killing an enemy while Arc-Knives are active restores Action Skill Duration. Activating Blade Fury causes Rafa to fire a volley of Acid STRM Gliders in front of him and end Arc-Knives. |
