I was around halfway through the hollow moor realm and had partly completed some quest when mobs became very easy to kill. I am set to 'champion' both when i rest and when i open portal.
when i started the realm, the difficulty was as expected, now i can 1 or 2 hit even the toughest mobs. i changed nothing
Comment to clarify. Realm card shows a difficulty of 60, but when entering realm on champion or nightmare difficulty shows (and plays) 37. I am not sure when this happened, maybe when i did the southmost bunker? It does not hamper play, just makes it all too easy.
