It’s pretty hard - I die quite frequently but generally only the first time - I don’t use the barrels & I only long rest when I basically outta spells. I’ve not played any dos games before & I’m really enjoying this.
I think if your finding it pretty easy you’re well versed in the mechanics & do quite a lot of scouting & planning before combat. I’d likely do better if I was a little more patient and took that approach more often - I’m learning too.
