The game writes the name with a zero, Fr0st-EE5, and players shorten it to Frostees. The legs are a Hunter Exotic, so Titans and Warlocks cannot equip them.

Rapid Cooldown is the Exotic perk of the legs, and it pays you for sprinting in 2 ways.

• Faster abilities: while you sprint, your grenade, melee and dodge recharge faster.
• Frost Armor: sprinting builds stacks of Frost Armor, and while you hold any stacks your Stasis weapons deal extra damage.

Frost Armor is the Stasis buff that stacks up and lowers the damage you take. With Frostees the stacks come from sprinting alone, so they reach you on any Hunter subclass, and any Stasis weapon in your loadout cashes in on the damage bonus.

Bungie gave Rapid Cooldown its Frost Armor half in Monument of Triumph, the final content update of 9 June 2026.

Frostees have no quest of their own. They sit in the random Exotic pool, and the game opens 4 roads to them.

1. Exotic Engrams: the Collections entry names Exotic engrams and very rare world drops as the source. Bring every engram to Master Rahool in the Tower on your Hunter.
2. Rahool's Focused Decoding: each page lists the Exotics of the class you play, so open it on the Hunter. Novel Decryption aims an engram at legs you have never collected and costs 1 Exotic Engram plus 1 Exotic Cipher. Precision Decryption makes a fresh pair once Frostees are in your Collections, for an engram, Glimmer and Ascendant Shards.
3. Ada-1: her Exotic Archetype Focusing rebuilds an Exotic you have discovered with the archetype you choose. An Exotic Requisition Order is the token she takes for that trade.
4. Xûr: Fr0st-EE5 is on his Exotic armor list, and his stock on the weekend of 7 November 2025 carried the legs.

Novel Decryption is the direct road for a Hunter who has never owned the legs. Where the engrams themselves drop is in our Exotic Engram farm guide.

Every Exotic armor piece rolls an archetype, and the archetype names its primary and secondary stat. A Frostees drop can land on any of 12 archetypes, while Ada-1's focusing offers the older 6.

Archetype	Primary stat	Secondary stat	From Ada-1
Grenadier	Grenade	Super	Yes
Demolitionist	Grenade	Class	Drops only
Brawler	Melee	Health	Yes
Skirmisher	Melee	Weapons	Drops only
Specialist	Class	Weapons	Yes
Reaver	Class	Melee	Drops only
Paragon	Super	Melee	Yes
Colossus	Super	Health	Drops only
Bulwark	Health	Class	Yes
Siegebreaker	Health	Grenade	Drops only
Gunner	Weapons	Grenade	Yes
Powerhouse	Weapons	Super	Drops only

Rapid Cooldown already speeds up your grenade, melee and dodge, so a primary stat on Grenade, Melee or Class stacks on top of the perk. The dodge is the Hunter class ability, which makes Class the stat behind it.

Of the 3 archetypes Ada-1 can focus for that plan, Grenadier fits grenade loops, Brawler fits melee builds and Specialist fits a dodge build. A Stasis weapon build leans on Gunner instead, the archetype Bungie describes as weapon-centric.

Frostees hand you Frost Armor on every sprint. These Stasis pieces check for that buff and give more while you hold it.

Piece	Type	What it does with Frost Armor
Grim Harvest	Hunter Stasis Aspect, 2 Fragment slots	Picking up Stasis shards adds stacks. With stacks up, Stasis and Kinetic final blows can shatter the target, and damage you take refills class ability energy.
Whisper of Rime	Stasis Fragment	Your stacks last longer and the stack cap goes up.
Whisper of Chains	Stasis Fragment	Kills while you hold stacks can drop a Stasis shard.
Whisper of Reversal	Stasis Fragment	Melee damage slows the target while you hold stacks.

Grim Harvest and Whisper of Chains feed each other: Chains turns kills into shards, and Harvest turns each pickup into more Frost Armor. More loadout ideas are in our best PvE builds guide.

A Pro logs in to your account and plays activities with a high Exotic drop chance until Frostees drop. Work starts within 1 to 2 hours of checkout, and the order page plans about 1 day.

• Never owned them: pick the order option for legs that are missing from your Collections.
• A stronger copy: add the high-stats option.
• Everything else stays: every item and resource that drops on the way is yours.
• Watch it live: add a stream to the order.

The order guarantees the Exotic, and the Frostees order page lists every option. Not sure which archetype suits your build? Ask in the chat on this page.
