ok so I completed every single quest and subquest in the game aside from ''Tomb Of Varn'', the hive and the control center. I'm trying to get through tomb of Varn but I'm having wayyy too much of a hard time.I cleared out, Eel infested waters, Dragonsand, Paradise Valley, Hermit's isles and Sweet water. Despite this, I'm only level 75. I need to gain some more levels but most maps are cleared and the only ones really worth doing take over 2 in game months to reset.
Where is the best place to gain some levels in the end parts of the game??
