I disagree with you about the idea of nerfing the Wizards. Yes, on one hand, they should be more accessible than other races, but on the other hand, they should be stronger than the priests of other races. After all, unlike the priests of Elrath/Malassa/Urghash, etc., these Wizards practice absolutely any kind of magic. (because, as far as I know, there was practically no forbidden magic in the Silver Cities, and our Wizards of the House of Chimera come from there.)
So, I suggest we think about who should be placed on the 3rd level of this Faction.
A similar creature could be the NCF Troglodyte, which has 96 hit points, 6-10 damage, 10 defense, 7 attack, 7 skills, but its speed and initiative are lacking (4), growth rate is 2, level 3.
Mages usually have a growth rate of 3; the Chimera mages can have the same, 50 hit points, etc.
