Our group happens upon a clearing containing a cultist and his followers, who are swarms of rats we have just watched become diseased.

DM: Everyone roll initiative.

Bard OOC: Are we fighting the rats? Maybe they’re friendly.

DM: …They seem angry.

Cleric OOCThey’re swarms of diseased rats.

Bard OOC: Well, we don’t know!!
