I'm building a steelbound two-handed 20th level fighter for a one off game. I've got all his feats and skills spec'd out but I'm struggling to decide on which 3rd level spells to use. Does anyone have some good recommendations? He is LN and will be/have been a Hellknight. His weapon of choice is a Scythe. I have no knowledge of what I might be up against nor what my teammates are playing.
Angelic Aspect (paladin), Channel Vigor, Dispel Magic or Greater Stunning Barrier (any of several lists), Horrific Doubles (medium) or Contingent Action (sorc/wiz) could all be useful. If you're a half-elf Paragon Surge for sure.
