Affable Cube

Cheerfully bantering when given a chance, the little earth elemental in this cube of granite desperately wants to be helpful.
Skill required: Geography
Benefit: When you activate this consumable, you may create a wall of earth within [Medium] range. This wall consists of a number of 5 ft square sections equal to your character level, with each section adjacent to another section. Each section of the wall is an obstacle and has 50 HP. Each section may be treated as a creature for the purposes of targeting with attacks and effects that deal damage and for the purposes of area effects that deal damage. Each section cannot make saving throws and is hit by any attacks targeting it. If an effect would damage a section on the section's turn, it is damaged on your turn. Once a wall section reaches 0 or fewer hit points, it is destroyed. The wall may not be placed in such a way that it occupies the same space as a creature, mount, or another object. At the end of the [Encounter], the wall cheerfully vanishes into a promptly appearing disposal chute which just as promptly vanishes as well.
