My list of suggestions/ideas

[*Product of Void]

you want a script to summon creatures off an object? I have had a few of those.

One I really liked it would look through a bag and create those on the creature then equip them.

was kinda neat so everyone had different henchmen.

[*Theban Soldier]

Another way to make custom summons (and have them be balanced) is just to give different appearances to the same creature.
