I've also noticed another thing. HP in Into the Odd - considering ItO:Remastered rule as written - and Cairn should not be the same. This is because ItO doesn't include the the "gang up" rule, which means that damage on a single creature is summed up, so HP should generally be higher than it is for Cairn. The "gang up" rule shows up in Electric Bastionland.

Hi everyone!
Thanks for the pointers! Some conventions were adopted when converting and they are disclaimed in the pdf (Including the CHA / WIL difference).
Stats were calculated trying to meet middle ground across different rulesets. Perfect fit is very hard to achieve, if at all possible. I believe it's close enough to provide the options present without being too far from optimal.
