What's a good gun or bomb for grievers, especially in confined spaces? I tried the spine cone with very limited success, and the needle shot is slightly better but not that great. Haven't managed to pick up a magnus, but I've heard quite different stories about it so I can't really judge if it's good. I know toothpicks will do well, but I'm allergic to melee combat and I'll prefer not to use swords.
Oh, and I'm (still) in T2 btw.
Shivermist -> Then Blitz Needle :P
