Undead Servants I

Wielding necromantic energy you manipulate a corpse to do your will, serving you in its undeath. When you begin casting this spell choose whether you are Creating undead or Binding undead, following the description of the chosen effect below.
Upon casting this spell you must consult the following chart, which details the cost required to Create or Bind the various levels of undead. The level you cast this spell with will determine the points you have at your disposal, only gaining the points for either Creating or Binding matching whichever you chose when initially casting the spell.

Creating. When creating undead all corpses or body parts that would be animated are required as material components and therefore must be within 10ft of you throughout the spell's casting. Upon casting the spell choose undead stat blocks for each corpse, of CR equal to that indicated on the table. Then confirm with your DM whether the stat block is fit for play (your DM has the ultimate say over what stat blocks you can or cannot use.) The materials present must feasibly represent the stat block chosen, some stat blocks may require additional components or magics for their creation (Up to DM discretion).

Binding. Binding is a different process than that of Creation, when Binding the targeted undead must remain within 10ft of you for the spell's casting time. When Binding, target any number of undead within 10 ft of you equal to the number and CR of undead you may bind according to the table. (Determined by the spell's level)
You may target undead to Bind which is higher CR than what could be Created with the spell, doing so comes with a risk of the Bind failing. When targeting an undead of greater CR than your spell's level, the undead must make a Charisma saving throw against your spell save DC, the spell failing on a successful save, on a failed save the spell continues unimpeded.
When targeting an undead that is already Bound and within 1 mile of their master you must make an opposed check with your spellcasting ability modifier. The spell has no effect on a failed check and continues as normal on a success.

On your turn you may take a bonus action to command your undead, choosing to command one or multiple undead, all undead chosen follow the same command and fulfill it to the best of their ability, continuing the action until the command is fulfilled or they are issued a new one. Some undead may be more intelligent and the DM may allow them to act semi-independently rolling initiative separately but taking cues and commands from you. Commands range from targeting a creature and choosing the undead's movement for the turn to a simple task such as guarding a chamber or space. Unless commanded to do otherwise, undead will take the dodge action and wait, only reacting to being harmed in which case they will defend themselves. 

Once the spell successfully Creates or Binds an undead they remain under the effects of the spell for 24 hours, after which the undead become unaligned and do as they wish until they are Bound to another's will once again.
