↖ Skills

• Hemorrhage: This skill takes the spotlight in our build, offering superior damage and attack speed bonuses when healthy. Combine it with enhanced Hemorrhage and bonus attack speed, and you'll be shredding enemies in no time.
• Unloving Energy: Allocate a single point to benefit from the damage boost, as it works well without overpower.
• Imperfectly Balanced: Allocate triple points here to take advantage of the bonus damage while mitigating the essence cost reduction. It synergizes perfectly with Hemorrhage.
• Blood Surge: Maximize the points in Blood Surge, as it directly affects your overpower and provides a significant heal per surge. It's a crucial skill for sustaining yourself and your minions.
• Enhanced Blood Surge: Allocate points here to further enhance the healing effect of Blood Surge.
• Paranormal Blood Surge: Invest points in this skill for overwhelming damage output. The faster you can dispatch enemies, the better.
• Blood Mist: Use Blood Mist for its overpower cooldown reduction and the skeletal warrior mastery, which complements your blood surge playstyle.
• Fueled by Death: This skill synergizes with your Ray Skeleton skill, granting your skeletons additional damage and healing. It eliminates the need for Corpse Explosion.
• Decrepify: Utilize this skill, along with cooldown reduction, to enhance your damage output. Combined with Corpse Tendrils, it becomes a deadly combination.
• Gruesome Mending: Allocate one point to benefit from the lucky hit chance, allowing you to fortify yourself for a percentage of your base life. The mini-novas generated by the Death Speaker's Pendant play a crucial role here.
