CookieRun: Kingdom Trials of the Nether Realm Season 6 Guide

To clear Trials of the Nether Realm Season 6 through Stage 10 in CookieRun: Kingdom, run a high-sustain composition built around Awakened Dark Cacao Cookie and Mystic Flour Cookie. Reaching and clearing Stage 10 unlocks a stable route to farm Legendary Toppings and Radiant materials, but later stages feature compounding wound debuffs, true damage spikes, and backline crowd control that will wipe fragile burst teams. Prioritizing defensive substats and continuous skill cycling allows you to clear the mode on full auto.

Recommended Auto-Battle Team Composition

This setup balances damage mitigation, defense shredding, and sustained single-target damage to handle multi-wave mobs and elite stage bosses without requiring manual inputs.

Role	Primary Cookie	Function	Supported Alternative
Main Tank	Awakened Dark Cacao Cookie	Absorbs frontline damage, applies injury, shreds enemy shields	Financier Cookie (with Magic Candy)
Secondary Tank / Bruiser	Burning Spice Cookie	Deals AoE burst, disrupts enemy formations, shreds DMG Resist	Crimson Coral Cookie
Primary DPS	Wind Archer Cookie	Delivers sustained single-target piercing damage against bosses	Creme Brulee Cookie
Secondary DPS / Enabler	Shadow Milk Cookie or Moonlight Cookie	Provides wave clear and periodic crowd control (stun/silence)	Golden Cheese Cookie
Main Healer / Buffer	Mystic Flour Cookie	Applies Apathy debuff, reduces team cooldowns, outputs heavy healing	Snapdragon Cookie

Awakened Dark Cacao anchors the frontline to absorb heavy opening strikes and soften high-defense targets in Stages 8 through 10. Mystic Flour Cookie is essential for auto consistency; her Apathy debuff slows enemy burst tempo, preventing incoming damage spikes from interrupting Wind Archer Cookie's channeled attacks.

Required Topping Sets and Substat Breakpoints

Raw level and star promotions are not enough to survive Stages 8, 9, and 10. Your Cookies must hit specific Damage Resist (DMG Resist) and Cooldown thresholds across their toppings and Beascuits.

Frontline Cookies

Awakened Dark Cacao Cookie: Equip a full 5-piece Solid Almond set. Target a minimum of 48% DMG Resist combined across toppings and Beascuit rolls. Aim for at least 8% Cooldown so his defensive shield activates before the first wave boss lands heavy basic attacks.
Burning Spice Cookie: Equip a 5-piece Solid Almond set (or a hybrid set with Searing Raspberry if your frontline survives easily). For stability on Stages 9 and 10, run pure Solid Almond with secondary CRIT Resist substats to absorb splash damage safely.

Midline and Backline Cookies

Wind Archer Cookie: Equip a 5-piece Searing Raspberry set. Substats must include at least 25% DMG Resist to prevent one-shot deaths from stray elite projectiles. Allocate remaining substats to ATK, CRIT%, and Cooldown.
Mystic Flour Cookie: Equip a full 5-piece Swift Chocolate set. Reach a hard Cooldown breakpoint between 24.5% and 28%, alongside roughly 30% DMG Resist. This guarantees continuous healing uptime and prevents team wipeouts during uncurable wound phases.

Best Treasures

Equip treasures that supply cooldown reduction and attack scaling over extended engagements:

Sleepyhead Jelly Watch (or Squishy Jelly Watch): Mandatory. Minimizes cooldowns to ensure defensive shields and healing fields remain active back-to-back.
Old Pilgrim's Scroll: Grants a flat, passive ATK buff required to punch through the elevated defense pools of Stage 8–10 bosses.
Disciple's Magic Whistle: Grants bonus CRIT and DMG Resist to your top two damage dealers (Wind Archer and Burning Spice).

If your frontline struggles to survive on Stages 9 or 10, replace the Disciple's Magic Whistle with the Sugar Swan's Shining Feather for a revive safety net, or Librarian's Enchanted Robes to accelerate Wind Archer Cookie's normal attack speed. The Watch and Scroll should remain equipped in all variations.

Stage 8 to 10 Boss Strategies and Troubleshooting

While Stages 1 through 7 can be cleared with standard investment, Stages 8, 9, and 10 feature distinct threat windows that can disrupt an automated run.

Stages 8 and 9 Wave Hazards

Backline Silence and Stun (Stage 8): Enemy mobs frequently silence your damage dealers right before mini-bosses execute sweeping attacks. Mystic Flour Cookie must have high Cooldown (24.5%+), ensuring her cleansing and healing cycles remain active across wave transitions.
Targeted Backline Damage (Stage 9): Unshielded Cookies will drop quickly to stray area attacks. If Wind Archer Cookie falls before reaching the stage boss, re-roll your Beascuit or topping substats until his DMG Resist reaches at least 25%.

Stage 10 Final Boss Execution

The Stage 10 boss enters an enraged state once reduced below 50% HP. During this phase, it unleashes an arena-wide slam that inflicts heavy knockback and continuous burn damage.

Enter the final boss wave with your Cookies' active abilities ready to cycle.
Let Awakened Dark Cacao Cookie engage first to apply injury and shred the boss's shields immediately.
If auto-mode mistimes your healing loop during the enrage transition, switch to manual controls as the boss approaches 50% HP. Hold Mystic Flour Cookie's skill and activate it immediately after the slam lands to wipe the burn debuff and restore team health.
Keep Wind Archer Cookie shielded so he can finish the remaining health pool during the recovery window, successfully completing Stage 10.
