That's all the accomplishments I can think of for now, as for disaccomplishments...
DIS: I haven't participated in wars nearly as much as I would've liked, I think the most I've done was 60 or so waves during the Bloodmoon War.
DIS: My Mana Potions are completely un-upgraded.
DIS: I'm only Rank 3 in the Arena.
DIS: Even with the Story Book Collection, I haven't completed all the quests through the Frostval and Mogloween story lines.
DIS: I haven't built up the patience to farm for the Peculiar Visor yet.
DIS: I didn't buy DoomKnight soon enough to have access to DmK V1, which is too bad because its game-breaking Life Carve sounds like a lot of fun to play with.
DIS: The current version of DoomKnight is still super overpowered, and that means I use it for almost everything. I still have fun with the game, but I think I'd enjoy it a bit more if I was a bit more varied.
DIS: I've blown through almost all of the 40,000 Dragon Coins I got when I purchased the Doom Knight Package.
DIS: I haven't played through Book 3 yet, and I'd like to replay Book 1 & 2 to regain context for the story in Book 3.
DIS: Perhaps my biggest disaccomplishment, I didn't play the game during its prime. I forgot my login info and lost interest in DF from about 2010 or so until 2015. I missed out on so much and trying to catch up after all that time was tough.
