Hey started playing last week and loving it so far even though i basically was throwing myself to enemies for my first 15 runs.
there are two things I've come across though. (I'm on v3.9)
Spoilers below
1) when fighting a boss in a dungeon and you kill them without destroying the shield you actually get the rewards of exp and gold without them dying and staying at low health you also do not go to the next turn allowing you to farm the boss with not fear of thirst and hunger
2) on the riftstone of sands island it doesn't have any shore tiles meaning you can get stuck as you can't get on your boat without being on a shoreline tile.
on an unrelated note is there a way to teleport your character out of the middle of the ocean (i tried to use wayfarer whey to teleport to my home and I'm stuck in the ocean, i've tried to kill my character by starving myself but i got health regen that's out healing it.)
