Hey, Excogitator! Sorry about that. The guide was made a very long time ago. If I remember, I was going to expand on the achievements but ended up not enjoying the game very much, so this was the remnants.

This really isn't a guide. You haven't explained anything, not even one achievement. Granted most are self-explanatory but some need clarity. You provide no clarity for any achievement. You just copy and pasted the actual achievements. Everything here I can read on the achievements page for the game. Am I doing something wrong? I made a purple weapon and I didn't get the "distillation" achievement. I don't expect an answer.

Ok never mind, I googled it and there are apparently little arrows next to the minions parts that let me spend digger souls to upgrade them, I have never noticed those arrows rofl.

There is an achievement that simply says "upgrade any part in a minion" but I have already upgraded so many parts in my minions and still haven't gotten this achievement... am I missing something? or is that achievement just bugged? I noticed it only has an 8% completion rate on steam, so unless it does not mean replacing parts with higher rarity ones, then I am assuming it's bugged?

Alternatively, if you wish, there is a mod for this game on Nexus that allows you to revisit previous floors, allowing you to kill the 1000 mobs needed for those achievements (it resets the floor, bosses included, but you can swap to the floors you have already unlocked). This is a nice quality of life mod that also allows you to train new teams if you so chose to do so, or farm items, etc.

Small discovery, might be useful for those trying to fill the Humonarium. If you are missing one of the random bosses from the first 4 floors, you can quick save on More Pain! Or Cakewalk difficulty, go up, and zoom out the map and check near the exit which boss has spawned. Reload if it's not the one you want and repeat until it's the one you need! :)

I think filling the Humonarium should be one of the last things you achieve, then you can just reset the floors for the kill 1000 enemies achievements on the floors you require. ^.-

Erratum 2: You exchange 3 parts with a chance to get a better one through Transmutation (the cube), not transmogrification. Sorry.

Erratum: The Houndmaster is actually called the Bounty Hunter, for clarity's sake.

For the minion achievements, upgrading the parts through transmogrification (better chance of legendary part if Iratus is high level) or builder's souls (costly, but guaranteed upgrade. 20 souls to upgrade from common to uncommon, 40 to upgrade to rare, and 80 souls for that legendary upgrade. Overall 140 souls for ONE legendary part). The most reliable way will likely be through combat, with the help of the Alchemy talents that increase higher rarity drop chance, or through some events. The Excavation can also sometimes surprise you with a good quality part as well.

Loss achievements are pretty straight-forward. Craft only a skeleton on the highest difficulty, transmogrify all your leftover components until you have nothing left. Go into battle and let poor skelly die. You'll get a game over and 2 achievements at once (and perhaps more if you didn't do any alchemy...). The Canon fodder achievements are achieved either by reloading any time you lose a minion during are grinding towards higher difficulty achievements...OR! By using a Lich-based party that summons and sacrifices skeletons for healing or resetting Iratus' talents. (I personally used a Lich, Zombie and Bone Golem party. Feel free to equip them with items that buff or heal when an ally dies! You might find it as amusing as I did!)
