Does the School of Necromancy feature Command Undead have a usage limit? The feature does not specify the number of times I can use it, all it says is
As an action, you can choose one undead that you can see within 60 feet of you.
This feature does not seem to use spell slots or state the number of times I can use it in a day. Does this mean I can use this skill at will? Or I can only use this in combat because it requires an action?
If none of these are correct please clarify.
