I think we have to add in DOLCharactes databate, the ability timer value, for example i use the berserker fury.. well im a pretty vendo ^^; then if i try to reuse it the server send me a message: u have to w8 xxx second to reuse ... BUT if i relog the game the timer start from 0 so i can reuse the ability, this is valid for all timer , pvp invulnerability , ecc..
Sorry for my english, hope u understand the problem
