Uhh, some of these: Devour Life Blood Fueled Killing Stroke Seism Lumbering Necrosis Scorn Consume Devour/Fueled/Necrosis/Scorn would be the tops, if I had to pick one.
Force barrier. Pretty firking awesome. Shame sprite is so slow. Additional mentions go to superchamp stuff like adaptive and thirst for battle, and revere abilities. @kalasle not stunning sweep?
I am right there with you. The ability can be a bit funky when it comes to maneuvering around objects, but it is a great ability if you tend to run out of time on your turn Transplant is probably my second just because it's like playing Whack-a-Mole.
Sweep has always been a favorite of mine for its tactical utility. I'm also fond of Body Jumper, though it's a shame the Elsari Siren is so trashy.
big fan of ..hex.., cheap and efficient, ..swap.. might help in a pinch, and I hate that im a sucker for a good ..surge..
