The Sanctum is Riot Games' latest monetization approach through an exclusive loot-box system in League of Legends. This gacha-style mechanic allows players to gamble for in-game content, specifically targeting Exalted Skins and Mythic Variant cosmetics that aren't available through traditional purchase methods.
The Sanctum operates differently from League's existing loot systems, focusing exclusively on high-tier cosmetic content rather than general game rewards. In this article, we'll explore everything you need to know about The Sanctum, including how it works, its currency system, drop rates, and available skins.

How Does the Sanctum Work

The Sanctum operates on a roll-based system where you purchase Ancient Sparks, the dedicated in-game currency, then spend them on individual rolls. Each roll grants you a random reward from one of three distinct prize pools:
S Tier: The featured premium skin you're targeting
A Tier: Secondary rewards including Exalted Chromas, various skins, or Mythic Essence
B Tier: Lower-value items such as emotes, icons, or Mythic Essence
S Tier contains the main attraction, such as the Spirit Blossom Morgana skin when it's featured. A Tier offers mediocre prizes that still hold decent value, while B Tier provides the most common rewards with minimal worth.
The Sanctum can showcase multiple premium skins simultaneously, each with its own guaranteed acquisition threshold. This pity system ensures you'll eventually receive the S Tier reward after a specific number of unsuccessful rolls.
Exalted skins require a maximum of 80 rolls to guarantee acquisition, translating to 32,000 RP based on LoLDB currency conversion tool. Mythic Variant skins have a lower threshold at 40 rolls, costing approximately 16,000 RP for guaranteed ownership. The system essentially functions as a premium gambling mechanism where you're guaranteed to receive your target skin within the specified roll limit, though you might obtain it much earlier through luck.
How to Get Ancient Sparks

Obtaining Ancient Sparks follows a straightforward process with two main acquisition methods available to players.
Direct Purchase serves as the primary method for acquiring Ancient Sparks. You can buy them directly from the store at 400 RP per Ancient Spark. Keep in mind that Riot Games enforces a daily purchase limit of 250 Ancient Sparks.
Battle Pass Premium Tiers offer an alternative source for Ancient Sparks. Each Battle Pass includes 3 Ancient Sparks as rewards for progressing through the premium tier system. The Battle Pass provides significantly better value compared to direct purchases. You can buy a Battle Pass for 1650 RP and receive 3 Ancient Sparks alongside numerous other rewards including skins, in-game currencies, orbs, chests, and additional cosmetic items. This makes the Battle Pass worth 1200 RP in Ancient Sparks alone, plus all the extra content.
All Skins Featured in The Sanctum
The Sanctum has featured 6 premium skins since its launch, rotating between Exalted and Mythic Variant options. Each skin requires a different number of Ancient Sparks for guaranteed acquisition based on its rarity tier.
Skin Name | Rarity | Ancient Sparks Required |
---|---|---|
Arcane Fractured Jinx | Exalted | 80 |
Radiant Serpent Sett | Exalted | 80 |
Quantum Galaxy Slayer Zed | Mythic | 40 |
Sahn-Uzal Mordekaiser | Exalted | 80 |
Spirit Blossom Morgana | Exalted | 80 |
After Hours Spirit Blossom Springs Ahri | Mythic | 40 |
Exalted skins consistently require 80 Ancient Sparks for guaranteed acquisition, while Mythic Variant skins need only 40 Ancient Sparks. This pricing structure reflects the perceived value and exclusivity of each skin category.
Final Words
The Sanctum is one of League of Legends' most expensive cosmetic acquisition systems, requiring significant RP investment for guaranteed premium skins. With Exalted skins costing up to 32,000 RP and Mythic Variants at 16,000 RP, players need to carefully consider their spending before engaging with this gacha system.
