(I know I replied to you about this on Twitter but it bears posting here)
No current plans for a monster book but converting monsters from Troika! should be pretty easy.
The damage output of my monsters (although generated differently) should be roughly the same to the damage output of Troika! creatures, so you can use those monsters with their damage tables or vis versa.
Stamina is about the same and Disposition is just another way of saying Mien.
Armor and Initiative are a bit different. Initiative in that monster stats have no effect on it (barring special abilities). Armor is typically a bit higher in AZAG, you can convert Troika! monsters by assuming 1 Armor = 1d6, 2 = 1d8, etc, or thereabouts.
Monsters in AZAG also typically have 2 special abilities that sometimes introduce special mechanics, this may make them a little more powerful than Troika! enemies in some circumstances.
