Variant: Summon Demon
The demon chooses what to summon and attempts a magical summoning.
A marilith has a 50 percent chance of summoning 1d6 vrocks, 1d4 hezrous, 1d3 glabrezus, 1d2 nalfeshnees, or one marilith.
A summoned demon appears in an unoccupied space within 60 feet of its summoner, acts as an ally of its summoner, and can't summon other demons. It remains for 1 minute, until it or its summoner dies, or until its summoner dismisses it as an action.
