This is a tower shield. Any attuned creature holding this shield can as an action hold the shield up to an opening or doorway no bigger than 10ft by 5ft and speak its keyword. At this point the shield laches to the opening or doorway (DC 16) and the zombie hand attached to the front animates. The check to see through the allusion is 16, a detect magic spell or similar also discerns that it is not a real zombie. 

Shields require the Utilize action to Don or Doff. You gain the Armor Class benefit of a Shield only if you have training with it.

Notes: Requires attunement by any class, race or alignment.
