I've been looking at the board, I believe the main reason you guys have been losing is because the characters are spread out. You can take advantage of the fact that Solstice doesn't have teleportation until after using legacy by moving everyone into more defendable formations. Here's what I propose for the first turn:

Furious : Move E
Araches/L33tzan : W, Mythslayer at row 3, column 1
Shuriken : N, NE, N, N
Sam : Move N
Faw/Uberbob : N,N
Grandma : Defend
Fooruman/Canoe : N, NW

This way, we have the spellcasters (Araches/L33tzan and Sam) in the corners, surrounded by three warriors each. On the next turn (hopefully after soltice uses legacy), Araches can use poison on solstice, and with any luck Solstice will use dispell on that. After solstice's dispell is used we can manashackle the succubus and manaflare grandma (Following Blackraptor's idea) Furious and grandma should definately be kept alive, because they are the brawns of the team needed to kill stuff really fast.
