Corrupted Knight

Corrupted Knight is the second summoned boss on Boss Island in Sea 1, sharing the same summoner as Blessed Maiden but bringing noticeably more muscle to the table. Its 750 million HP — 100 million above the Maiden — reflects a harder, slower fight that demands better-tuned damage before it becomes comfortable to chain.

Unlike the Maiden's near-guaranteed utility drops, Corrupted Knight's table is sparser and skewed toward rare cosmetics. Morgan Remnant leads at 15%, which is decent for crafting but far from guaranteed every kill. Alter Essence follows at 5%, and then the table drops off sharply: the Alter Armor Accessory sits at 1.5%, the Corruption Core at 1.3%, the Corrupt Tyrant Title at 0.85%, and the prestigious Corrupt Crown at just 0.5%. The Knight rewards patience more than volume — the cosmetic prizes are legitimately rare.

The practical approach is to weigh the Knight against the Maiden when deciding where to spend Boss Island summons. If you need rerolls, the Maiden is better value. If you are chasing the Corrupt Crown or Corrupt Tyrant Title specifically, the Knight is your target — keep expectations measured and treat each clear as a chance to chip away at those low percentages over time.
