i think something to defend yourself against gangbangs would be cool, although maybe too op, But for a succubus build would be cool
my main problem with sea witch was that when outnumbered, the gangbang killed me, that why i started playing abomination. But now, beeing able to make aoe damage (something that i just realise thanks to you :D xD), that wont be a problem, and seawitch gives you a nive bonus to your thoughness so you can do even more damage
