I'm not sure if this is a bug or just me missing something about palettes.
I've started using ZQuest 2.10 and am trying to make a "Gleeok (Fire, 1 Head)" guard an enterance on the overworld (dmap 0, level 0). I filled in the extra sprite palettes 1, cset 13 to my liking, but I can't find where the cset for its fire breath is. Currently, the Gleeok shows up, but the fire breath doesn't; you just get damaged and thrown back. I've tried flooding the palettes try to get anything to show up, but it's still invisible 😞. Fire from candles is still visable.
In the ZC192 version, the new enemy tiles rule seemed to handle this, but it appears as if that is gone.
