Many have seen me talk about but seeing this is a new rule I wanted to say it here myself.
You have 7 lives in 1 IRL year. (Unless you have "YOU CANT KILL ME!") move. This does not go for Admin NPCs (Such as Quest characters). [If you die when your already dead though... Guess what!? You dead for good still.]
UPDATE/REITERATION: Due to confusion, to reiterate the rules of the 7 lives, this is the effect of it. You are allowed to die 7 times without the 'YOU CANT KILL ME!' trait. Due to this, if you die an 8th time, you are stuck in the afterlife until the 1st of January, the following year. You do not die permanently unless you are killed in Hell, which is avoidable.
