Yeah, that took me a while to figure out. Parts of the "horde" UI need some work.
- There's no indication of how much of each type of damage you're dealing. (Just scaling factors, which isn't the whole picture.)
- There's a whole resource (nostalgia) whose quantity isn't even displayed anywhere in the game, except in parenthesis at the end of a long tooltip.
- The list of heirlooms isn't labeled, so it's just a list of random upgrades with no indication of where they came from. (Since "heirloom" implies some sort of physical object, like "relic," and that's just a list of boosted stats, it seems unlikely that they'd have anything to do with each other.)
- I still can't figure out what "damage conversion" means in an item description.
Overall, it doesn't quite meet the dev's stated goal of "detailed explanations about mechanics in-game" yet :)
