Description
Filled with a caustic mixture that discharges when stepped on, these tetrahedral caltrops present a much more dangerous hazard than their mundane variety. A typical bag of these 1-inch health and safety nightmares contains 20 caltroozes. Small bubbles of acid forming and bursting inside the caltroozes cause them to roll and shift.
Caltrops: As an action, you can spread a single bag of caltroozes to cover a 5-foot square. Any creature that enters the area must succeed on a DC 15 Dexterity saving throw or stop moving and take 1 piercing damage. Until the creature regains at least 1 hit point, its walking speed is reduced by 10 feet. A creature that moves through the area of the caltroozes at half speed makes the saving throw against them with advantage.
Corrosive Chaos: If a creature fails the Dexterity saving throw, roll a d4 and consult the table below to determine what additional effects take place:
Corrosive Chaos Table:
| d4 | Effect |
|---|---|
| 1 | The acid in the caltroozes discharges in a single burst. The creature takes an additional 6d6 acid damage. |
| 2 | The acid takes on lubricating qualities. While the creature's speed is reduced by the caltroozes, it must succeed on a DC 15 Dexterity saving throw at the end of each of its turns or fall prone. |
| 3 | The acid coats the creature's feet, continuously eating away at them. While the creature's speed is reduced by the caltroozes, it takes 1d4 acid damage for every 5 feet it walks or climbs. |
| 4 | The acid causes a creature's feet to temporarily deform. While the creature's speed is reduced by the caltroozes, it has disadvantage on Dexterity saving throws. |
After a creature fails a saving throw against the caltroozes, they are emptied of acid, and you can't use this property again until you spend 10 minutes decanting a phial of biomantic acid into all the caltrops. The caltroozes can still be used as regular caltrops that deal magical piercing damage.
