Monster Summoning IV

This spell is much like the 3rd-level spell monster summoning I, except that this spell summons 1d3 4th-level monsters. These appear within the spell’s area of effect and attack the caster’s opponents, until he commands them to cease, the spell duration expires, or the monsters are slain. These creatures do not check morale; they vanish when slain. If no opponent exists to fight, summoned monsters can, if the wizard can communicate with them, and if they are physically capable, perform other services for the summoning wizard. The material components of this spell are a tiny bag and a small (not necessarily lit) candle.
