Bigby's forceful hand is a more powerful version of Bigby's interposing hand. It creates a man-sized (5 feet) to gargantuan-sized (21 feet) hand that places itself between the spellcaster and a chosen opponent. This disembodied hand then moves to remain between the two, regardless of what the spellcaster does or how the opponent tries to get around it.
However, the forceful hand also pushes on the opponent. This force can push away a creature weighing 500 pounds or less, slow movement to 10 feet per round if the creature weighs between 500 and 2,000 pounds, or slow movement by 50% if the creature weighs more than 2,000 pounds.
A creature pushed away is pushed to the range limit, or until pressed against an unyielding surface. The hand itself inflicts no damage. The forceful hand has an Armor Class of 0, has as many hit points as its caster in full health, and vanishes when destroyed. The caster can cause it to retreat (to release a trapped opponent, for example) or dismiss it on command.
The material component is a glove.
