Miscellaneous Achievements

 
Curious
 
Find a secret
 
 
This achievement is basically unmissable, you’ll unlock it for entering any of the secret rooms, some floors require you to enter a secret room to progress, so you shouldn’t have too much trouble unlocking it.
 
 

 
Artisan
 
Craft an item
 
 
Simple achievement, all you need to do is craft an item at the forge which is guaranteed to spawn on floor 3. To craft an item you require either a blade & a hilt or an axe/mace & a shaft, combine them in the crafting menu then rearrange them however you like and craft it to unlock this achievement!
 
 

 
It’s like a real RPG!
 
Complete a quest
 
 
You can acquire a quest from one of the talking heads you’ll come across every now and then. They give a few variations of quests all of which are quite simple, you shouldn’t have too much trouble finishing them.
 
for example:
 
– Spike 2 enemies at once 3 times
 
– Kill 3 enemies with a single explosion
 
*You can only have 1 quest active at a time, and it will carry over to the next floor.
 
 

 
Good protein
 
Eat 50 critters
 
 
You can unlock this achievement by eating the small bugs that spawn commonly on tables and shelves.
 
 

 
Merciful
 
Save Ava
 
 
After completing the final boss battle Ava will be lying on the ground, to unlock this achievement you need to take her with you when you unlock the door. She takes up a lot of inventory spaces so you’ll have to leave a lot of loot behind.
 
 

 
Righteous
 
Kill Bindrick
 
 
To kill Bindrick you need to keep hitting the columns holding up the balcony he’s standing on. Once they break he’ll die and this achievement is yours.
 
 

 
Once more into the fray
 
Re-enter Slasher’s Keep
 
 
Once you’ve finished the game, if you load the same save file you’ll be able to start the game again and unlock this achievement, however you’ll retain all of your stats and items and the enemies will be a lot harder.
 
*If you choose the infinite dungeon the achievement won’t unlock
 
 

 
Live to fight another night
 
Use a prisoner chute.
 
 
The prisoner chute can only be found on the 3rd floor and later with the perma death mode enabled. It’s a chute that will send you back to the beginning of the game the same way it would if you died on a normal run, this way you can replay early levels and farm items without permanently dying. It’s a small room with a chute and a lever, pull the lever to go back to the beginning and unlock this achievement.
 
*You can select perma death mode after finishing the game at least once
 
 

 
 
 

Character Unlock Achievements

When starting the game you only have the option to play as either a Northerner or an Amazon, the rest of the characters require specific tasks to unlock.
 
*Unfortunately there seems to be a bug at the moment where sometimes characters and achievements you unlock during the end of the game won’t actually unlock even though it says you unlocked them, there’s no fix for this yet that I’m aware of. The game should be updated, and this bug fixed soon hopefully.
 
 

 
A gross talisman
 
Find the lucky monkey paw
 
 
To unlock the Sasquatch you need to kill Ava. She’s the final boss that dual wields swords. Once you’ve killed her you’ll be able to pick up the monkey paw and this character and achievement is yours.
 
 

 
A monkey’s whisper
 
Find the jade monkey
 
 
Unlocking the Undead character is very similar to the Sasquatch, however you need to kill Bindrick, the sorcerer instead of Ava. To kill him you simply need to keep hitting the wooden pillars holding up his balcony, once he falls you can pick up the Jade Monkey and this achievement and Undead will unlock.
 
 

 
A considerable sacrifice
 
Satisfy the god of blood
 
 
The demon is a little bit tricker, to unlock him you need to sacrifice yourself at one of the red altars. They only spawn after you’ve beaten the game at least once, however it doesn’t need to be on the same save file. Unfortunately they’re pretty rare.
 
 

 
 

 
A regular everyday human person
 
Let yourself be consumed
 
 
This character is the hardest to unlock, it requires you find an ‘energized slime sample’ and an ‘energized acid sample’ in the same run, these are only dropped by the blue and green slimes. If you’re lucky enough to have both samples, once you get to the library levels you can find a brewing stand which you can interact with and combine the samples, once combined you’ll acquire a potion, and once you drink it you’ll turn into the Jelly-man and unlock him for future runs (as well as this achievement!)
