Outside of the normal 3 (Single target, DoT, AoE), they have Toxicon (which is just ED combined with Ruin II), Phlegma, and Pneuma. All of which also heal your Kardia target as you attack and feel good to use. 2 of them don't even waste any of your valuable healing resources. Pneuma does (being an AoE heal with the line AoE), but it still feels so good to use.
