Replacing Weapon Animation With a Spell

This might be difficult with the vanilla Fight command. Weapon animations are a little more limited than spells and other attacks, so I don't think it would be as simple as changing the animation properties of a weapon. You could try modifying the Shock command at C1/BB49 and C2/171A. There is also a pointer at C2/B4CC that you would need to modify. You could also try writing a new weapon animation script, maybe a combination of the unarmed script at D0/7EF9 and the pummel script at D0/6EE0. Or maybe there's an easier way to do it that I'm not thinking of...
