Perses said: SRD There are several monster sheets in the SRD that seem to be missing a line of text in attacks that cause a saving throw against poison damage. These sheets will say something like "and the target must make a dc on a failed save, or half as much damage on a successful one" instead of the full text. For example, the Giant Spider's Bite should say "the target must make a DC 11 Constitution saving throw, taking 9 (2d8) poison damage on a failed save, or half as much damage on a successful one" instead. This seems to only be present on the Character Sheet tab, while the attack listed on Bio & Info will be correct. This bug has been reported in the past and fixed for Phase Spider and some other creatures, but its still a problem for the following monster sheets: Giant Spider Giant Wolf Spider Imp Purple Worm Assassin Spirit Naga Giant Poisonous Snake Guardian Naga Giant Centipede Giant Wasp Quasit Scorpion Spider Unfortunately I do not own a copy of the Monster Manual on Roll20, so I'm unable to check if there is a similar problem there. Almost every statblock that has something like the Giant Centipede's or Wyvern's poison save is done incorrectly. The extra damage is being added to the Damage 2 field which gets rolled on a normal hit, and again on a critical hit. This is not how it should be. The correct usage would be to turn the damage in the description field into an inline roll or clickable button instead, like below. The problem with including the damage in Damage 2 is that inexperienced DM's will deal that damage to player characters without realizing it shouldn't be added or doubling it on a critical hit, which it would not be per the rules.
