Dewomer Vortex and Spell Fangs from Anauroch, Empire of Shade.
Dewomer Vortex is, without going into illegal amounts of detail, a level 3 spell which can dispel spells of level 3 or lower without dispel checks. But it can also simply auto counter these spells if they target you or have you in the area. It has a max spell-levels dispelled/countered limit. At levels 5-6 it's intensely better than dispel, and after that it remains as a very interesting niche use spell.
Spell Fangs is a level 4 evocation spell. But if you can get over that prejudice- Well, basically, as with any spell which creates dXes of things which each deal dXs of damage, incredibly amusing when combined with maximize spell. In this case, it's 1d6+2 tentacles with 2d6+CL damage each. Ranged Touch. BUT THAT'S NOT ALL: 30ft REACH WHIPS. YOU GAIN TEMPORARY HP EQUAL TO THE AMOUNT OF DAMAGE DEALT FOR ONE ROUND. DURATION OF CONCENTRATION. BUY TODAY AND YOU GET A FREE- eh. whatver.
