Elasticity

You alter the properties of one object in range to make it bouncy and bendable. Target a nonliving object or portion of an object that fits in a 10 ft cube that isn't being worn or carried. The target takes on the properties of rubber, allowing it to bend and squish, while still retaining all of its previous properties that aren’t negated by this. For the duration, the target becomes immune to bludgeoning damage and has resistance to piercing and slashing damage. Additionally, any attack that would inflict bludgeoning damage instead pushes the attacker (if melee) or projectile (if ranged) back by the amount of damage they would’ve inflicted in feet. A melee attacker affected by this falls prone. For example, if an orc attempted to bash a elastic door down with a greatclub and would’ve dealt 5 bludgeoning damage, the door takes no damage, and the orc is pushed back 5 feet and falls prone.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the area you can affected increases by 5 cubic feet for each slot above 4th.
