1. One of the quests gives a Dead Rat. I don't know what it's supposed to be used for.
2. Another one (the one where you must clean out the "scroll reading enthusiasts") gave two of the same recipe. I'm not sure if that recipe I had before or not, but it gave two of the same recipe.
3. When you take on a quest and your entire army gets beaten, about 10 or 20 turns later you win the quest automatically and get the rewards even if you didn't beat the guardians.
3. I'm not sure if it would not be such a big deal on higher difficulty levels, but on the lowest difficulty level, I can put three mana berries on 3 or 4 or more different items, and get 9 or 12 or more mana for each kill with that unit. When you're the Tinkerer, and the dwarf gets the ability to have another turn when killing a unit, you can quickly rack up lots of mana. Not sure if it would be the same with a non-Tinkerer or a harder difficulty level, that would need to be tested.
4. Again, I don't know how the Thrifty Potioneers skill is meant to work. It doesn't seem to do anything currently. Not sure about the skill for re-using scrolls.
5. After killing 5 or 6 units in a row, Drogan doesn't continue to get extra turns. Not sure if this matters too much, as this many consecutive turns can allow you to kill most armies.
6. Sometimes you get two of the same dialog, for example after saying something to the SK. If you get something from it, I'm not sure if you actually get it twice, but it's possible.
7. It seems that talking to the SK counts as a Quest, and can give Lore/Sovereign Skill points from the Tinkerer abilities.
8. When you don't have any SK threat, and you kill a Lieutenant, dialog says Sorcerer King Threat +3 but instead it is set to 5. Should probably show +5 SK threat instead, since it always puts SK threat at maximum, at least if you say to the SK that you are coming to get him. Not sure what happens when you grovel, but probably not much different.
9. Some crafting items don't have a listed effect for enchanting. Either show the Enchanting effect in the Enchanting screen if the crafting ingredient has one, or don't allow those items to be used for Enchanting.
I still find the game quite fun. Haven't tried harder difficulty levels yet - what are the differences?
