Holt's Interposing Hand (3.5e Spell)

You create a translucent hand made of pure force that appears in the same space as the creature you designate. The hand automatically expands to take up the same amount of space as the target creature, moves with the creature to stay in its space, and grants them all the benefits of cover. The hand cannot be destroyed by damage and is immune to most magical effects, but can dispelled or instantly destroyed by a disintegrate effect.

Each turn, you may command the hand to move to protect another individual (within range) of your choice as a free action. If the creature the hand is protecting leaves the effective range, the hand immediately and automatically returns to protecting you.

Focus: A glove.
