Threads of dark power leap from your fingers to pierce up to five S or M corpses you can see within range. Each corpse stands up and becomes undead. You decide whether it is a zombie or a skeleton, and it gains a bonus to its attack and dmg rolls equal to your spellcasting ability modifier.
You can use a bonus action to mentally command thees undead creatures, if they are within 60', issuing the same command to all of them. You decide what action the creatures will take and where they will move during their next turn, or you can issue a general command (i.e. guard a chamber). If you issue no commands, the creatures do nothing except defend themselves against hostile creatures. Once given an order, the creatures continue to follow it until their task is complete.
The creatures are under your control until the spell ends, after which they become inanimate once more.
When you cast this spell using spell slot of 6th level or higher, you animate up to two additional corpses for each slot level above 5th.
