Here's a concern I have about level up.
If the heroes get super buff by the 2nd or 3rd tile already, what's the power creep gonna be like if you level up and keep the best items during a campaign?
You don't keep equipment; whatever you get gets turned into crystal shards that you use to level up your character. It sounds like monsters will also level up so the game is going to escalate to where red dice will be worthless and you're mostly rolling greens along with those new yellow and purples. That's my understanding at least.
