After the player joins the alliance, the player can attack the Giant Corrupted with members of the alliance.

After successfully defeating the Giant Corrupted, non-NFT teams will have the opportunity to obtain low-star hero advancement materials.

When the NFT team defeats the 2-star and above giant corruption, there is also a chance to obtain Serum, Zombies and ascended Materials. The higher the star rating of the Giant Corrupted or the higher the damage caused by the player, the higher the chance of the player getting the Serum.
