Spell slots added to a monster

Hello, i have found no way to add spell slots to a monster i created. That monster is added to my main character at extras and it has spell slots. I need to add them in some way in order to better be able to play it.

Thnxs.

Monsters don’t get “spell slots” the way PCs do, those slots just get listed in the descriptions. Like THIS.

One thing you could do as a workaround is to add the functions to a magic item with charges, and then you would at least have some way to track them.
