Master Reanimator

Whether through intensive study or the dark blessing of a divine or otherworldly force, you have mastered the art of raising undead. You gain the following benefits:

• Undead you summon, raise or create with necromancy spells (such as Animate Dead or Create Undead) add your level to their hit point maximums. If they would already recieve a hit point maximum increase from another source, they add the highest of your Intelligence, Wisdom, or Charisma modifier to their hit point maximums instead.
• Undead you summon, raise, or create with necromancy spells add your Spellcasting Ability modifier to their weapon damage rolls. If they would already receive another bonus to their weapon damage rolls, you use whichever bonus is higher instead of stacking this one with that one. If you have more than one Spellcasting Ability (such as through multiclassing), you choose which one this feat uses for its effects when you gain it (which is not subject to change after selection).
• With your DM's permission, you can use Animate Dead to create skeletons and zombies from the corpses and bone piles of non-humanoid creatures and creatures with a size smaller or larger than medium. Your DM has the statistics for these skeletons and zombies. Your DM may require you to secure expensive ritual components, perform a sacrifice, or meet any other requirement they wish to raise particularly large or powerful skeletons and zombies. Your DM may also decide to have skeletons and zombies larger than medium count as multiple skeletons or zombies for the purpose of determining how many you can raise and reassert control over.
