Usage
Passive
- [Passive, In Slot] Assault Mode: When this skill is mastered, the first time the user would die, their death is prevented and user enters Assault Mode. This has a 1200 Second Cooldown, Assault Mode is active for 400 seconds (Both configurable)
- [Passive, True] Hellblaze: When mastered, gain Black Flame.
Active
- [Active, Held] Full Counter: This mode functions just like Reflector, however just for Projectiles, any projectile reflected, is automatically sent back towards the original caster, with tracking logic. The skill is reflected at x2 the power. (4x when mastered). Both configurable
- [Active, In Slot] Dark Prominence: While in slot, attacks deal bonus Dark Damage on hit. (10%, 20% when mastered)
- [Active, Held] Divine slayer: While held, begin charging a power scale up to 10, when released, the entity you're looking at is hit by the a number of attacks from the player, up to 10 + 1 (X + 5 when mastered), This should probs use the sword slash particle and black flame particle. Maybe have it do dark damage and fire damage instead of physical? But yeah, scale off of attack damage.
