AI-Generated Deep Dive Summary
Diablo 2’s new warlock class has been cracked wide open by YouTuber Coooley, who discovered a clever exploit allowing players to achieve near-immortality using a pet demon as a shield. By maximizing the Blood Oath skill and equipping specific gear, Coooley’s build redirects an impressive 89% of damage to their demon companion, rendering them nearly invincible in combat. This groundbreaking discovery highlights how the warlock class can be tweaked to dominate even the toughest enemies, including the game’s new expansion bosses.
The trick lies in pairing Blood Oath with a highly resistant demon and essential items like Treachery and The Rising Sun. These tools not only reduce incoming damage but also convert minor injuries into healing effects, further safeguarding the player. Coooley’s strategy hinges on recruiting a demon immune to most forms of harm, ensuring it absorbs the brunt of attacks while the warlock remains unscathed. This approach may lack high damage output, but its defensive capabilities make it an unstoppable force in prolonged battles.
While the build requires specific gear and preparation, its simplicity makes it accessible to players willing to invest time in crafting the right setup. Blizzard has yet to address this exploit, leaving a window of opportunity for players to experiment with this innovative strategy before potential nerfs arrive. For gaming enthusiasts, this discovery underscores the importance of creativity and adaptability in mastering game mechanics, offering a fresh perspective on how to dominate even the most challenging content.
