Additional things I've noticed:
9) Swords in graveyard only ever generate as 2-4 damage. Blacksmith can generate swords for 5-10 or even 10-20 damage. While otherwise, blacksmith and graveyard generated armors have the same defense stats.
10) Several stats are poorly explained. Like what is the difference between Strength, Dexterity and Stamina? Hovering over them says nothing.
11) Typo with Strength and Attack Speed when hovered over.
12) What does +1 dodge mean? Am I limited to 1 dodge per combat, and this increases it to 2? Or is it +1% chance to dodge?
13) Healing rooms on deeper floors don't heal for more damage. And visiting a potion room at max 5 potions, does nothing... doesn't even heal the lowest party member.
14) Going deeper doesn't seem to do anything, other than increase the risk of death. I don't feel like I find more or better items at floor level 3, vs floor level 1. I don't feel like the amount of gold is better. I just feel that my characters are more likely to die, for no benefit.
15) Reroll passive seems like a good idea on paper, but poorly implemented. For 1000 gold, your passive must really suck on an otherwise well rolled character. And with the new passive possibly worse than current one, I'd at least suggest it roll 3 random ones, and you choose which of the three you'd prefer.
16) Rare Death Shield and Epic Death Helm, always rolls the exact same stats every time they drop.
