Overload

Whenever you cast a spell that requires Tyros Attunement, gain 1 Overload stack. Stacks up to 5 times.

On basic attack: consume all Overload stacks to deal +3 Thunder Damage per stack to the target.

At 5 stacks: the next Fulmination spell that deals damage consumes all stacks to deal +100% Thunder Damage and has +100% Stun Chance.

If no new stacks are gained in 3 turns, lose 1 stack.
