Empty Sack

An uncommon trinket that applies a status effect at the start of each battle (StatusOnBattleStart) and spawns additional entities on the battlefield (SpawnExtraThingsOnBattleStart). Empty Sack is a strong battle-opener — extra spawned allies or hazards can shift the fight before it begins, and the battle-start status gives your cat an immediate advantage. Pairs well with Feed Bag if the spawned entities inherit your passives.
