Cleon
Legend
I'll await Cleon's final lookthrough before moving on, as this was a complex one.
Shouldn't the impaler use a 1.5 Str bonus when wielded as a single weapon, since presumably the Geran will use both hands?
Also, there's no point listing the impaler twice in the Attack Line, since both ends do the same amount of damage, just different types.
Revising...
Attack: Claw +7 melee (1d4+3) or impaler +7 melee (2d4+4/x3)
Full Attack: 2 claws +7 melee (1d4+3); or impaler +7 melee (2d4+4/x3); or impaler +5 melee (2d4+3/x3) and impaler +5 melee (2d4+1/x3)
Apart from that tweak I think we're OK.
