The most frustrating monsters to encounter as a PC...besides rust monsters

[Kelb_Panthera]

Living Love's Pain. Fight an ooze, discover afterwards everyone you ever loved is dead.

Does the fact my immediate response to this was to giggle make me a bad person?

Actually, when Charm says 'threatened', do they mean on the grid or general hostile action?

WotC is never clear in these things. I'd lean quite heavily toward the "in general" reading but YMMV, so ask your DM.
