This spell causes a field of rubbery black tentacles to appear, burrowing up from the floor and reaching for any creature in the area. http://www.d20pfsrd.com/magic/all-spells/b/black-tentacles
I cast illusion and create a seven foot vagina, and then escape while everyone's favorite hentai scene unfolds.
Evard's Black tentacles, really hated it when they took the iconic names away from spells. Bigby's hands, Melf's acid arrow, Mordenkainen's Disjunction, etc. James took my first action, but lets make it more realistic to the theme shall we. Summon a Succubus to the mercy of the tentacles, mwhahahaha. Seriously though I would probably just Counter spell you.
I'm wearing a Ring of Freedom of Movement, so I ignore your tentacles and then kick you in the ankle for casting it at me.
