What this would add to earthsmash is when you click while facing earthbendable blocks in a formation like raiseearth where there are air blocks on your side and the opposite side of the earthbendable blocks, in a 3 by 3 square it would send the included blocks away from you and the other blocks in a line. If the 3 by 3 square of blocks hits an entity, the entity would be sent flying away dealing 4 damage by default. This suggestion is so short xD
