I'm now thinking about the Bosses of the dungeons. Once you have the Relic of the dungeon you're going to be rolling +1 die for all rolls in the dungeon, including against the Boss. So if I've got my legendary gear attached to +3 stat and I just choose to use that stat, regardless of what the trials say, I've got about an 87% chance of beating him.
I don't like to min/max. And this game seems like it would feel too hollow to cheese it. I'm just big into analyzing rules and offering suggestions or insight.
