Description
Within this sturdy, corrosion-resistant polyhedron is a phial of polyhedrooze ooze; a caustic substance with remarkable powers of biological alteration.
Caustic Calamity: As an action, you can press a button on the polyhedron, crushing the phial, and then toss the device up to 60 feet away. The resulting chemical reaction produces an explosion of acid in a 20-foot radius. Each creature in the area must make a DC 15 Dexterity saving throw, taking 4d6 acid damage on a failed save, or half as much damage on a successful one. In addition, the reaction produces unpredictable biomantic effects on a failed saving throw. Roll a d10 and consult the table below to determine the effect. If a creature comes under an effect lasting 1 minute, it can make a DC 15 Constitution saving throw at the end of each of its turns, ending the effect on itself on a success.
Polyhedron Effects:
| d10 | Effect |
|---|---|
| 1 | The acid stops regeneration and healing. The creature can't regain hit points for 1 minute. |
| 2 | The acid coats creatures, dissolving them. The creature takes 2d6 acid damage at the start of each of its turns for 1 minute. |
| 3 | Parts of creatures' bodies meld together. The creature has disadvantage on attack rolls for 1 minute. |
| 4 | The acid fuses feet and footwear to the ground. The creature is restrained until the end of your next turn. |
| 5 | The acid fuses the eyelids shut. The creature is blinded until the end of your next turn. |
| 6 | The acid causes creatures' skin to become phosphorescent. The creature is under the effect of the faerie fire spell for 1 minute. |
| 7 | The acid causes growths to appear and disappear on creatures' bodies, hindering their actions. The creature is under the effect of the bane spell for 1 minute. |
| 8 | The acid causes creatures to shrink. The creature is under the reduce effect of the enlarge/reduce spell for 1 minute. |
| 9 | The acid fuses mouths shut. The creature is under the effect of the zippit!* spell for 1 minute. |
| 10 | Roll twice on the table, rerolling any further 10s and duplicate results. |
Once this property of the item has been used, it can't be used again until the next dawn and a new phial of polyhedrooze ooze has been installed in the device.
