The Kuo-Toa cannot reasonably fold their arms. They always impale themselves with their clawed fin hands.
There is only one Redcap that manipulates the Kuo-Toa. It also does not look "mirrored". Why are there shown two Redcaps?
The BOOOALs Arms are declared as a melee weapon in the description. In the flavor text they are also described as an improvised weapon. Why can't they be used as an improvised melee weapon? We lack improvised melee weapons...
