And Ohalland. Don't forget Ohalland. He was a Blitzer/Summoner. =D
On the Blitzer "Slots" Overdrives, you may want to do a teeny bit of rewording.
"...then re-roll any 1 or 2 die, if you wish."
Once you read it a bit the meaning becomes obvious, but the first couple of times I thought it meant to re-roll any die showing a 1 or 2. I can imagine it confusing people at first (Assuming they eventually figure it out at all), so maybe you might reword it...?
[EDIT] I forgot to read page 7. Ergo, this post may be full of idiocy and is obviously out of place. For those who care to know, I typed it thinking the end of page 6 was the last of the thread, and I haven't read page 7 yet, so I'll go do that...
