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.

Where to find Voidcritters

Purchasing them from a Computer - The easiest and fastest way to collect Voidcritter Cards is to order them through the Computer. Sims can purchase a single booster pack for §25 and can purchase 5 booster packs for §125.

Trading Cards - The most sociable way of getting Voidcritter cards is that children can ask other children to trade Voidcritters in which the child must pick a Voidcritter card (preferably a duplicate) to swap for a random Voidcritter card given by another child.

Looking for Discarded Toys - Another way to get Voidcritter Cards is to look in trashcans and bins for discarded toys as Sims have a chance to find a Booster Pack.

Limited Edition Foil Cards
When collecting Voidcritters, there is a chance Sims can get limited edition foil cards, which will have unique golden bolt designs on them but don't have any effect on gameplay.
