Derren said:Actually it isn't powerful at all. Unless there are additional information about charm effects the only thing the kiss does is that the character interposes himself when he is standing directly next to the Succubus and he won't attack her.
Other than that the victim is free to do what he wants including killing the Succubus minions or bosses.
Naw, the power has the Charm keyword. The DMG or more likely the MM will have the rest of the information on what can be done with Charm. I'd assume it would be similar to what could be accomplished with 3e Charm spell:
"Protect me, good friend! Your friends are possessed, I'll escape through the window"
