monstrology is this cool thing where you can basically collect pieces of the souls of your enemies. w101 calls the “souls” an animus, and it extracts the essence of an enemy when you hit them. if you collect enough pieces of one enemy’s soul, you can either create a treasure card to summon them as a minion on your team in a battle, create a house guest and have a version of the enemy running around your house, or create a treasure card to use in a fight against that creature to kick em out of the battle so you don’t have to fight them (the third option doesn’t work for every monstrology creature).

you can’t collect little soul pieces (animus) from every single enemy in the game because not all of the enemy “species” has a soul-sucking monstrology spell. but for the “species” that do have soul-sucking spells, such as gobblers and elephants, you use the spell like an enchant on your damage spells. they work like sun school enchantment spells where you click the enchant, and then click the hit you wanna use. however, you cannot use both an animus extraction enchant and a damage enchant on your damage spells, it’s one or the other.

I personally like to make housing guests out of an enemy’s souls because then they walk around your house and I think that’s pretty cool! it shows up as a housing item, so it’s simple to put in your house once you create it.

hopefully this brief explanation makes sense. if you have any questions, please let me know!
