@Boggy:
The only corrections I'd point out are that Haste (both Araches' and Shuri's) can affect any target and the rule about spellcasting is you can cast one spell per turn (with the exception of Sam's Unload Mana spell, which will let him still cast spells after other people). There's a few little details on the Frost Lawyer that aren't correct, but they are all in your favor and not that important since I don't have a chance to use that spell much (for instance, it's not entirely infinite).

@File:
I guess you could leave, but you'll have to come back eventually and you aren't likely to find any shotgun ammo between then and now.
