Just for the fun of it, I thought I’d try leveling the base Mage class to 100. I certainly got a kick out of trying it in Grim Dawn, which actually has a secret medal if you get to level 100 and complete the base game in Hardcore (on Ultimate difficulty) without choosing any mastery classes.
Kind of unfortunate that the mastery is tied to the story, so I’m certainly missing those Idol slots you get. The bonus passives would be nice too, though I’m about to max out my Mage passives pretty soon so I guess it doesn’t matter. Well, I still got some work to do though. I can only imagine what those later levels are going to feel like.
