Okay, I'm now working through those Terror Monkey mutations. The first one I hit, Large, both moves the size of the Monkey up to 0 from -1 (with the accompanying effect on Toughness) and ups its Bite damage from a d4 to a d6.
Now the first I can just do by having the thing add +1 to Toughness; it might be a little confusing but its probably better than messing around with bootstrapping around another version of Size and hoping it overwrites properly.
The question I have is about the damage die though; before I go through it, is there a way to just upgrade the extent weapon die one step (as there is with attributes and skill dice) or do I get to try putting in a second version of Natural Weapon also labelled "Bite" with a later timing and see how it all works out? I thought I remembered something that upped a weapon step somewhere, but I can't find it so maybe I'm imagining it.
