Undead Shield

Command your undead minions to protect you!

When being struck by an attack, be it melee, ranged, or spell (this does not include any AoE spells or any AoE damage included in a spell, such as Ice Knife) you can command 1 reanimated undead you control within 5ft of you to block the attack.

Each undead minion used in the spell absorbs up to their Hit Points in damage. If the attack's damage exceeds the undead's Hit Points the remaining damage transfers to you, or the next undead if casted at a higher level. 

If any of the undead minions have Undead Fortitude, they must make a DC 15 Constitution Saving Throw for the effect to take place. The damage still transfers to you or the next undead even if Undead Fortitude activates. Undead Minions that survive with Undead Fortitde, in this way, are unable to use the ability again, until they are reanimated again.

The undead protect you until the start of your next turn, or until all undead used in the spell have lost all their Hit Points.

At Higher Levels. Command 1 additional reanimated undead per Spell Slot above 1st to absorb damage from the attack.
