I've decided to bang up a quick "fix" for the Firstbloods. Changed stuff in bold.
Code:
Firstblood
12 AP, mapmove 2, size 4
14 attack, 12 defense (starting with 10 for Pirians), 14 precision
25 HP, 15 strength, 13 protection(starting with 7 for Pirians)
14 MR
12 morale
1 encumbrance
weapons: Greater Starburst (basically a big version of the AP non-fire attack), Big Fire Sword of Doom or somesuch (my idea: sort of like the First Sword, but less super-powerful and a bit more fiery death. Still some normal damage, though)
fireshield 14?, heat 10? (these guys are epic heat-producers), maybe #iceprot -2
75 poison resistance, 100 fire, 25 cold (as said before, their heat is going to melt some of the stuff before it gets there)
By the way, they'll probably all have fire 1 or 2+.
Some of this stuff might make Prians/Firstbloods a bit too powerful, but oh well. I have to leave now, I've spent a lot longer than I intended. I'll get to the rest of your reply later.
