Corrupting Fever is a spell that grants a similarly-named buff. While the buff is active, hitting enemies will inflict stacks of Corrupted Blood on them that deal physical damage over time, up to a maximum of 10 stacks.

Skill functions and interactions

• Casting Corrupting Fever costs life instead of mana. Spending enough life while the Corrupting Fever buff is active will refresh its duration; the spent life threshold is much lower than the cost of Corrupting Fever itself.
• Inflicting a new stack of corrupted blood on a target will refresh the duration of all stacks currently on that target, as is common with all corruped blood mechanics.
• Hits do not need to deal damage in order to inflict corrupting blood stacks.
• As it does only Damage Over Time, it is not affected by modifiers to Spell Damage.
• Proxies such as Totems, Traps and Mines will not inflict corrupted blood on hit as they cannot inherit the Corrupting Fever buff from the player.

Trivia

The skill gem's description erroneously describes the debuff inflicted as "Corrupting Blood"; however, the Helmet Enchantment and gem quality correctly lists the debuff as Corrupted Blood, which it shares mechanics with other sources of.
