Sword character.

Power up that makes your next hit, whatever it is, do bonus damage and put a debuff on your target for X seconds. If the target tries to cast a spell with the debuff on, he or she takes that amount of bonus damage again and is silenced for X seconds. This does additional things based on which move you trigger it with. Basic attacks get that trigger this give it a lower cooldown.

Counterattack that dashes you behind the target, dealing damage. Applies your power up's debuff for additional time if used to trigger it.

360 degree AoE slash around you. Can thus apply your power up to multiple targets.

Flash that teleports you a small distance forward.

Super move that charges up for a short time, then does a massively powerful slash in front of you, dealing huge damage. If this triggers your power up, it gains more bonus damage.
