(This is Eligor's Alternate Art ability.)
With this ability, Eligor starts without any Vengeance token but he can have up to 5 of them.If he takes damage, he gains as many tokens as points of damage he took.
When he takes damage, he can choose to discard tokens to reduce this damage,1 token per point of damage.If he takes full damage, gains a token.
But if he starts with 0 tokens, can gain max 1 per beat and must lose 1 token during the Ante phase, this ability seems useless because he never has tokens to discard.
It's a nonsense.
