This spell is like monster summoning, except that the spell is forgotten when the caster learns a higher-powered version of the spell. This causes the caster to lose the ability to cast this lower-level version and it even disappears from his spellbook (this spell is normally transcribed from a scroll). Either 2d6 skeletons or 2d4 zombies may be summoned.
The undead appear at the end of the casting and fight to the best of their ability until slain, the duration expires, they are released, or they are further than 30 yards from the caster (the caster may not intentionally move out of range, nor may the undead for they are not free-willed while under the spell). At such time, they return to their point of origination.
The material component is a lit candle inside a small bag.
