I run a game of Rise of the Rune Lords and we converted from Pathfinder to 5th edition D&D. I've kept the player characters at the same suggested level as in the book. My 4 players are well equipped and we have played RPGs for 4-5 years together.
The problem: the adventure seems so difficult at PC level 9 (2 at lvl 8 due to level drain).
For example: a recent encounter with two stone giants in the Hook Mountains. One player has gone down and then they decided to take a full rest before venturing to the clanhold. They are afraid of more than two ogres.
I'ts my first time running a campaign at that level, but 5th edition chars seems to be more powerful than in Pathfinder.
Did I do something wrong?
