When you Exhaust a Talent or party Talent you turn it face down and put 4 tokens on it and then for a personal talent you remove a token at the end of each of your turns until they are all gone. What about a Party Talent when do you remove recharge tokens from it? End of each round? End of each players turn? End of each turn for the player that used the Talent?
Also can you only use a talent on your own turn?
