Blood Hit system is similar to Weapon Taker's Overheat, as it both drains their health when they use it. The two classes do, however, have some major differences that should be noted:
- Unlike Weapon Taker, Dark Knight does not acquire a damage buff after consuming HP.
- She also has various skills that allow her to regenerate that lost HP, making her Blood Hit HP-to-damage conversion much safer and easier to use.
- Similarly to a Weapon Taker with Mercenary Behavior, Dark Knight and Crimson Avenger don't take damage from Blood Hit activation when below 20% HP.
Blood Hit's HP consumption is based on how much damage a skill would deal at that moment, taking into account your own Physical Attack, any Physical Attack buffs, the skill's skill trait, as well as the damage range on your weapon that is affected by the Maximize stat. Critical hits and Skill Damage Increase/Decrease effects are ignored.

The color of Elesis' Gale and Annihilation auras becomes darker, due to the incorporation of darkness.
- Similarly, Sacred Templar's Dilution also changes the colors of his Way of the Sword Auras, but brightens their colors instead.
