power: lift double the weight i should be able to
weakness: recovery time is a day where i can only lift half what i should be able to :[
so once in a while i'd power through a piece of furniture or something, but then the ability would go on cooldown for a day where i'd be half as strong as normal.
also, that way if someone were to ask me to do it again to prove how strong i am, i wouldnt be able to. once a day sort of deal.
i think it's a fair trade off.
