Forbidden Knowledge

Forbidden Knowledge

It is said that those who acquire the Forbidden Knowledge develop an otherworldly control over eldritch beings. On use, summons a Boss at 50% health (with 50% of the boss's initial damage credited to the user). No base damage is credited, however, meaning the user won't receive Standard Loot unless they attack after the Boss is summoned.
