Siege Hand

Create a colossal invisible hand that can shove, crush, carry, or block. Each turn, choose one: make a melee power attack for 5d10 force damage, push a creature 30 ft., carry up to 2,000 lb., or provide three-quarters cover to one creature.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
