That would be my second choice, though you have a bias because it's the closest to serving an eldritch horror. Telekinesis can't invoke the power of PAIN and through that insanity though. I envision giant blood golems which were once our enemies and have been manipulated through constant pain to become monstrous rage-filled abominations who only wish to end their existance while punching as many things' chests through their hearts as possible on the way.
If precise enough, we can set off the nervous systems in our enemies. Total pain.
I may be slightly biased in that I think telekenisis is the coolest power, but that's because blood magic needs blood to work. Telekenisis just needs anything.
Setting off nerves just isn't as good as torturing our enemies to death in the messiest way possible. And it doesn't have slitting our wrists and causing the blood to rapidly undergo nuclear decay.
Why? Debate is probably the most essential element of a good suggestion game. The fact that we're arguing means we care about the choice and are relating our view on the topic before coming to a decision together. Overall it leads to better suggestions and a better game experience.
Been reading too many debates
This always.
As in I've been reading too many debates over which fictional entity would win in a fight and thus I spout off debate-style points whenever I'm arguing anything and yeah. ANYHOW, let's stop discussing me and get back to the game!
