Chest of Endless Legs

Portable Storage. The Chest of Endless Legs can hold up to 250 lbs or 30 cubic feet of non-living material inside its extradimensional space. If the chest is destroyed, either via damage or overfilling, its contents spill into the 5 ft square the chest was previously occupying.

Extradimensional Implosion. Placing the Chest of Endless Legs inside an extradimensional space created by a handy haversack, portable hole, or similar item instantly destroys both items. Each creature in a 10 ft radius Sphere of the implosion must make a DC 15 Dexterity saving throw. On a failed save, they are pulled in to the center of the blast. On a successful save they remain unharmed and unmoved. If multiple creatures or objects are pulled, they all take 2d6 force damage as they slam into each other.

Eager Follower. The chest instinctively follows its summoner, moving as closely as possible without requiring commands. Additionally, the chest knows where its summoner is as long as the two are on the same plane of existence and within 1000 ft of each other.

Protective Measures. The Chest of Endless Legs can choose to disallow someone from attempting to open it. Should the chest refuse to open, any creature attempting to open it must succeed on a DC (12 + summoner's Proficiency bonus + the spell's level if a spell slot was expended + any Lock bonus) Athletics check.

Leg Scramble. Melee Attack Roll: +1 (+ spell level), reach 5 ft. Hit: 1 (+ spell level) Bludgeoning damage.
