Mesmerizes a target in place within a 30 yard range so that they are not able to attack, cast, move, or use any other abilities. Any damage caused to the target will remove the effect. Seduction has a 1.5-second casting time and is channeled, so the
Succubus can't perform any other action while seducing and can be interrupted. This ability only works on
humanoids and lasts for 15 seconds, barring
diminishing returns or damage -- any damage inflicted on the target will break Seduction instantly.
Using Seduction on the same target within 30 seconds will have a shorter duration the second time and an even shorter duration the third time, and won't work at all after that. Furthermore, Seduction is on the same diminishing-returns timer as Fear/Howl of Terror -- meaning that it doesn't help to switch from one of these spells to another to keep one target at bay.
Seduction can be set to auto-cast; the AI does nothing when you're facing one opponent, but with more than one, it's fairly good at picking one enemy you're not fighting and seducing it.

Seduction on other players is controlled by the Diminishing Returns Rule, which means that you can't seduce a player an unlimited number of times.
Not only that, but Seduction and Fear are on the same Diminishing Returns Rule, preventing alternating use for long times.
