I'm restarting my character, following my accidental X-Box 360 wipe. I'm recreating the same character, Thadious, but I decided to up the difficulty to Master.
It's definitely a different way to play the game, for sure. I've had to change my tactics, and I've noticed that certain things that were more of a luxury on Adept (like summons, for example) are actually way more viable and helpful this time around. I kinda like the new tactics that now come with the difficulty.
It is frustrating, having 10 restarts if I stumble upon a group of bandits, but so far, it's also a more engaging experience.
I'm only level 7 though, so I don't know how it's gonna go from here on out, but so far I'm enjoying it.

I went from Expert (110 hours) to Master (8ish hours) and it's extremely hard.
