Nether Queen Cookie Build Guide

Skill

River of Tartrus

• 14s cooldown
• Lv.100 values

The waters of Tartrus purify removable debuffs from allies, then restore HP and grant an HP Shield along with DMG Dampening and DMG Resist buffs. When Nether Queen Cookie's skill heals an ally beyond their Max HP, the excess is converted into a Shield. Inflicts Soul Shackling, Branded Soul, and Injury on enemies. Nether Queen Cookie gains Soul Fragments periodically and upon meeting certain conditions. Once she has enough Soul Fragments, she grants the Ring of Tartrus and its power to ally Cookies (excluding herself) just before they are defeated, triggering up to 2 times per battle. However, allies who already have other Immortality or Invulnerability effects active before being defeated are excluded. Nether Queen Cookie is not affected by removable Incapacitated debuffs, Silence, Cooldown freezing, or Cooldown recovery reduction. At the start of battle, she gains the Ruler of Tartrus buff, and grants herself an HP Shield once while inflicting DMG and ATK reduction on enemy Cookies. If there is exactly 1 Healing Cookie on the team, grants DMG Dampening and CRIT DMG Resist to self. Once per battle, when defeated, she grants herself the Ring of Tartrus and her Cooldown is reset. If an enemy Cookie gains Invulnerability, it is removed after 1 sec.
