Mutators, buffs and debuffs (XBOX)
As far as I can tell there is no way to pause the game and hover over these icons and read the tooltips. Dungeon mutators you can somewhat get to if you scale the UI small enough so the character sheet won’t block them.
Now you just need to rely on the wiki and memorize the icons basically. Making the icons interactive when the game is paused would help a great deal.
