I had an interesting battle today and something happened that I couldn't understand. Is there something I don't know or is this a bug in the game?
Rule of Battle: Noxious Fumes: All Monsters start the battle Poisoned.
Serpent of Eld was not affected by this rule, and did not start the battle with poisoned until the end of the battle.
This is the first time I have encountered such a situation, maybe there is something I don't know? Maybe a bug in the game? It has been a very interesting situation for me. I will be glad if the players who know answer.
Thanks in advance to those who replied.
