Kunimatyu said:They still can't attack the succubus for the rest of the encounter, though, and there's nothing saying the succubus can't follow the PC. Depending on the definition of "attack", the succubus may even been able to pull the PC closer with a dominate.
Yeah, but they can attack any other monster on the field, so unless the succubus is the only opponent, that's just going to result in the PC moving away to attack other things and the succubus wasting everybody's time. At worst, in most encounters, it means people delay their actions so the one guy can move away. It'd only be really useful if the PC can also be kept from moving.
If the succubus is the only opponent, then she'd be best off kissing one PC, trying to keep moving to constantly hug him, and keep Dominating another PC into attacking the party. Otherwise, I still say she should kiss an allied brute/soldier/whatever and use it as a tank while she Dominates the party.
