I've got a player whose level 8 PC died last session due to a combination of bad rolls, a Confusion spell, and forgetting some of the abilities he had access to.
Now he's made up a replacement character: A Reincarnated Druid (level 8) with deliberately low HP that he plans to use as a critter-summoner and 'occasional suicide bomber' (his words). He's got Str, Dex, and Con all at 6 or 8--deliberately low stats and weak AC. In essence, he's eager to get killed regularly so he can roll on the Reincarnate table over and over again. "Basically, I'm immortal!" he grinned.
Now, I know that there are limits built into the Reincarnated archetype; for example, if he gets killed a second time within a week, it won't function to bring him back. But this player is basically daring me to kill him and seems to think it will be fun for everyone if he dies all the time and keeps coming back in new bodies. As with many a jokester at the table, he's missing that it will only be fun FOR HIM.
Any suggestions beyond the inevitable "talk with the player"? This is not a player I know well and don't particularly like, but he's generally experienced and competent, and two other players adore him (which is why they invited him into my game).
