There is a bug in the Roll20 version of the Blemmyes monster. In the original source material (Tome of Beasts by Kobold Press), the first portion of the monster's bite attack reads as follows: Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 19 (4d6 + 5) piercing damage. The Roll20 version reads as follows: Bite: Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 19 (4d6 + 5) peircing damage plus 14 (4d6) acid damage. There are two errors in the Roll20 version: 1. It adds 14 (4d6) acid damage to the damage of the bite attack. In the original version, the acid damage is not part of the initial bite attack. Acid damage only applies when a medium sized or smaller incapacitated creature has been swallowed, and it only begins to take effect on the swallowed creature at the start of the monster's next turn. 2. The word "piercing" is misspelled as "peircing".
