Abyss of the Four is one of those events you don’t want to ignore. There are tons of hidden rewards, unique shops, exchange mechanics, and progression checkpoints that can boost your account if you take it seriously. The more you play and the higher your challenge level, the more valuable the rewards become.
If you’re grinding Cookie Run Kingdom, this event is worth putting time into. Below is a full breakdown of what matters, how to approach the event, and the best way to farm keys, clear bosses, and get everything possible before the event ends.
How the Shops Work
There are four separate shops based on the four beast cookies. Each one offers different types of rewards, so you’ll need keys from all four bosses to buy everything. The shops are:
- Mystic Flower Shop: Mainly chests and upgrade items
- Burning Spice Shop: Various resource materials
- Eternal Sugar Shop: Toppings and topping-related items
- Shadow Milk Shop: Cookie cutters and gacha resources
Your first priority should be Soul Stones and Soul Cores, especially for the beast cookies. You’ll need around 1,000 keys total to buy all soul stones from all shops, so start farming early.
If you struggle against certain bosses, you can exchange keys at a 2:1 ratio. It’s not efficient, but it helps if one boss is too hard to farm.
How to Farm Keys Efficiently
Keys are earned by defeating bosses, and the higher your challenge difficulty, the better the reward. For example:
- At Challenge Level 30, you get around 80 keys
- At Challenge Level 40, you get 100 keys
If difficulty 40 is too hard, it’s fine to stick to the highest level you can reliably beat. What matters is consistency because you’ll need to clear each boss at least 40 times to unlock all story rewards and extra event bonuses.
Important Progression Rewards
There are multiple layers of rewards in this event:
- Shop Rewards
- First-Time Challenge Rewards
- Story Unlock Rewards
- Season Ranking Rewards
You don’t get the first-time reward unless you clear the boss at the required minimum challenge level. For example, if the reward says minimum 31, clearing at 30 won’t count.
To finish everything, expect to complete:
- 40 clears for each boss
- Full story unlock requirements
- Minimum power level checks for each stage
Yes, it’s a grind, but the payoff is solid.
Recommended Teams and Builds
Some bosses are harder depending on your comp. Based on testing, here’s the general difficulty tier:
- Easiest: Burning Spice
- Medium: Eternal Sugar / Shadow Milk
- Hardest: Mystic Flower
The most effective team setups include:
- Eternal Sugar (Main Damage)
- Wind Archer
- Silent Salt (If available)
- Two supports such as Marshmallow Bunny or Cream Ferret
If challenge level 40 feels impossible, drop to 35, since below that you lose a cookie slot. Using five cookies helps survivability.
Best Recommended Powers (General Use)
These powers work well across all bosses and are considered the strongest options overall:
-
Supremacy of Power Boosts overall attack significantly and scales well at higher challenge difficulty.
-
Life Dominance Gives a large damage boost based on total HP, perfect for tanky teams and Eternal Sugar builds.
-
Damage Bypass (True Damage Modifier) Helps deal damage even against bosses with resistance or defensive scaling.
-
Strike of Bliss Gives invulnerability and boosts Light damage and crit stats. Strong against Shadow Milk.
-
Tyrant’s Wrath Helps counter Mystic Flower’s Apathy effect and boosts burst windows.
Best Power Combos by Boss
Below are the most optimized 3-power setups depending on the boss you’re facing.
1. Burning Spice
Best pairing focuses on fast clearing and exploiting Earth advantage.
Recommended setup:
-
Supremacy of Power
-
Life Dominance
-
Damage Bypass
(Optional: Earth Element Power if available)
Why: Burning Spice deals the lowest real-threat damage, making offensive builds the fastest approach.
2. Eternal Sugar
This boss rewards burst damage and steel damage scaling.
Recommended setup:
-
Life Dominance
-
Supremacy of Power
-
Damage Bypass
(Optional: Steel Element Power if using Silent Salt)
Why: Eternal Sugar’s mechanics are simple, and burst damage ends the fight before effects snowball.
3. Shadow Milk
This fight benefits the most from damage reduction and invulnerability tech.
Recommended setup:
-
Strike of Bliss
-
Life Dominance
-
Damage Bypass
(Optional: Healing or shield-based modifier if Pure Vanilla isn’t used)
Why: Shadow Milk hits hard. Strike of Bliss prevents wipe scenarios while keeping damage output high.
4. Mystic Flower
One of the hardest fights because of Apathy, heal block, and survivability checks.
Recommended setup:
-
Tyrant’s Wrath
-
Supremacy of Power
-
Damage Bypass
(Optional: Darkness or Steel Element depending on your DPS)
Why: Tyrant’s Wrath specifically negates Mystic Flower’s gimmicks and makes the fight manageable.
Best Element Buffs to Activate
Follow the elemental weakness chain for faster clears:
-
Eternal Sugar → Light
-
Shadow Milk → Earth
-
Burning Spice → Darkness
-
Mystic Flower → Steel
-
Back to Eternal Sugar (loop)
Always check the power info menu so you activate the correct element before a run.
Toppings and Stat Priority
Your highest attack and HP cookie will receive certain buffs depending on the stage. Eternal Sugar benefits the most from this, so aim to give them:
- High ATK
- High HP
- Cooldown and Crit depending on your survivability
If your team dies too quickly, swap some offensive toppings for damage resist.
Ranking Rewards
Like most competitive events, whales will dominate the top spots. However, even lower ranks still get:
- Rainbow Cubes
- Radiant Biscuit Dough
- Soul Stones
So even if you’re not pushing for rank 1, you should still participate.
Abyss of the Four is a rare event with layered rewards across story progression, ranking, shops, and challenge milestones. It may look overwhelming at first, but once you pick the boss you can clear easiest and start farming consistently, things move faster.
So, Focus on Clearing each boss at least 40 times, Buying every soul stone first, Matching elements for faster clears & Using exchange only if necessary! With the right approach, this event can leave your account way stronger than before. Good luck with your runs and make sure you farm every day while it’s active.
