Some further feedback:
1) Graveyard level 6 is too hard. I've lost 2 well geared squads to it, and only completed it once... and barely survived. You really do need a level 7+ party to do it, but you can't do graveyard at level 7+.
2) Party perks are definitely not being applied.
3) I'm not sure Dodge is being applied. Even with +20 stat, and I think dexterity is used for it, and its at 31, the character still regularly gets hit, and not actually seen them avoid damage entirely.
4) I think defense isn't reducing damage completely, as I have one character that has like 40 defense, and regularly takes 1 damage hits.
5) If you have too many loot items, you cannot select the middle two characters, to see if they need any upgrades. Usually a result of doing Gobbling keep at depth 5 or depth 6.
6) Too many rings at Emberforge generate with low rolls, despite appearing to be rare or epic quality. Cost a fortune, but why would I spend it on their low rolls?
7) Noticed with the Emberforge, that each item is generated at a specific tier, with the worst items generated at far left, moderate items generated in middle, and best items generated at far right. Thus at late game, you have to reroll constantly to get epics in far right slot, to have any upgrades.
