On the Wishlist are the monster modding commands
#clearweapons
and
#cleararmor
Those can allready be done with
#weapon 0
and
#armor "Nothing"
Including this in the next modding manual could be a simpler solution than including a new command (...don't know ...)
For side modding instead of the specific #summon command
#cast [commander type] ["Spell name" | Spell id]
might be not much harder and much more useful, because it would include scrying sides like the well of all waters and allow some new ideas (teleport gates).
-commander type would be -1 for "any commander" and 0 to 8 would be a mage of the according magic path numbered as usual.
(...Again, maybe it's not possible, maybe it is, don't know...)
