You summon undead that appear in unoccupied spaces you can see within range. You choose one of the following options for what appears:

• One undead of challenge rating 2 or lower
• Two undead of challenge rating 1 or lower
• Four undead of challenge rating 1/2 or lower
• Eight undead of challenge rating 1/4 or lower

An undead summoned by thus spell disappears when it drops to 0 hit points or the spell ends. The summoned creatures are friendly to you and your companions. Roll initiative for the summoned creatures as a group, which have their own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions. The DM has the creatures’ statistics.
