Manifest Charm of Mabar, the Endless Night

Charm

When you use a spell slot to cast a spell that animates or summons an Undead (including Animate Dead, Create Undead, or Summon Undead), you can expend the Charm (no action required) to treat the spell as if it were cast using a spell slot 1 level above the slot expended.
