Voidcritter

Voidcritters are a variety of monster card collectibles that are featured in The Sims 4: Kids Room Stuff. Voidcritter cards can be input into a Voidcritter Battle Station to battle against other Voidcritters or to be trained. Only child Sims can use Voidcritters on the battle station, as teens and older can only collect them. There are a total of 20 Voidcritters in a variety of names, rarities and elements. All Voidcritters start at a Power Level of 1 and with each training session they will go up 1 power level.

All Voidcritter cards have a +3 playful emotional aura.
