Purchasing this DLC grants a permanent benefit: for every 100 monsters defeated, you will receive a random-rarity (minimum Legendary) [Supporter] Material Pack. Opening a [Supporter] Material Pack will randomly grant one material of the corresponding rarity.
This DLC is the supporter pack for 《IdleDiablo》. Purchasing it unlocks an additional way to obtain materials: you can earn random materials by continuously defeating monsters, which effectively enhances the early-game experience.
