Millennial Tree Cookie is a Legendary Cookie in Cookie Run: Kingdom, built around the Support archetype. Support Cookies enable the rest of the team with buffs, debuffs, heals and shields. Legendaries are top-priority pulls if you're optimizing for Arena, Guild Battle, or Beast-Yeast. The current Mythras-tested loadout runs Ancient Root Peanut x5, with a Legendary Hearty beascuit and a Peanut tart for HP.
Support Cookies enable the rest of your team with buffs, debuffs, heals and shields, and the type is dominated by healers, shielders and DMG Resist givers. Some still show up on a damage chart: at max skill level Eclair's skill hits for 1,022.3% of his ATK, Olive's Black Bat for 930.5% and Pulpo's All, Wrapped Up for 1,914.5%. What no Support does is speed up the team's Cooldown. Jagae, Millennial Tree, Pom-pom Dough and Pulpo cut only their own, and the one ally Cooldown effect in the type is Jagae's skill resetting Manju's.
| Mode | Fit | Why |
|---|---|---|
| PvE Story | B | Helpful but not required. DPS-first teams clear faster. |
| Kingdom Arena | S | Top supports decide matches. Millennial Tree is meta-defining. |
| Guild Battle | S | Team ATK and DMG buffs raise every attempt's damage, and Linzer's Suspect applies to any boss regardless of debuff immunity. |
| Cake Tower | A | Late Decadent Choco tray tips name Supports: Pomegranate on 48, Millennial Tree and Frilled Jellyfish on 51, Star Coral on 53, Peppermint and Seltzer on 55. |
| Beast-Yeast | A | Enemies get Debuff Resist +40% or more in Episodes 1–4 and on every Hard stage, so debuff Supports face more resistance there. |
Mode fit ratings are based on the cookie's archetype, not their specific kit. A Legendary Support that's S-rated for a mode may still need build investment to actually clear top-tier content there.
Support Cookies amplify whoever your team is built around. Buff supports pair with DPS (Millennial Tree boosts team ATK, but only with no Defense Cookie on the team). Debuff supports pair with the damage type they amplify (Black Sapphire cuts enemy DEF by 20% for each Poison-type Cookie on the team, up to 80%). Combo supports pair with their named partner (Seltzer inflicts Stinging Fizz only when Menthol is on the team, and Menthol's Gas Explosion sets it off).

Build Tips
Legendary Beascuit: Standard Legendary quality is optimal for this cookie. Remember to fully attune all 4 symbols.
Cooldown Priority: Cooldown is the most valuable substat. Aim for the highest CD rolls possible on your toppings.
Tart Connection: Always connect your Peanut Tart to the toppings for the 6-piece set bonus substats.
Keep stats in purple range. Reset Beascuits until you hit optimal percentages (aim for 15%).
Legendaries require focused crystal saving. Expect 1-3 months per Legendary F2P with disciplined banner pulling and event participation. Pity counts carry over inside banner windows.
Top priority for the meta picks. Pick the role gap on your roster and chase the Legendary that fills it. Do not spread soulstones across too many Legendaries at once.
Legendary Cookies have no Magic Candy. Seven have a Crystal Jam instead (Black Pearl, Sea Fairy, Frost Queen, Moonlight, Stormbringer, Wind Archer and Fire Spirit), leveled with Life Jewels from Trial Grounds; the rest have neither.
