Mastery Monday is live — 2x XP, 2x Dust, and boosted Legendary and Mythic spawns

Mastery Monday runs all day today, September 7 — the weekly window where Sprites level faster, extractions pay double, and the two highest rarity tiers turn up far more often than they do the rest of the week. It is the best day of the week to turn Sprites you already own into Mastered ones.
When it runs
The event covers a full 24 hours from the Monday reset:
- PT — 6:00 AM Sept 7 through 6:00 AM Sept 8
- ET — 9:00 AM Sept 7 through 9:00 AM Sept 8
- Brazil (BRT) — from 10:00 AM Sept 7
- UK (BST) — from 2:00 PM Sept 7
- Europe (CEST) — from 3:00 PM Sept 7
- Japan / South Korea — from 10:00 PM Sept 7
- Australia (AEST) — from 11:00 PM Sept 7
- New Zealand (NZST) — from 1:00 AM Sept 8
There are no sessions to catch and no windows to miss this time — but every bonus stops the moment the day rolls over, so anything you were holding back for double Dust needs to be extracted before then.
What's boosted
- Spawn rates — Legendary and Mythic Sprites appear much more often.
- XP boost — level up your Sprites twice as fast.
- Sprite Dust — earn 2x Sprite Dust from extractions.
- Extra gear — complete daily challenges to snag extra Portable Extractors.
How to spend the day
Equip what you are closest to mastering. Doubled XP is worth the most on a Sprite that is already partway up the track, so slot those in first and leave the untouched ones for a normal week.
Save your extractions for today. Dust spends the same whenever you earn it, which makes one run banked today worth two of the same run tomorrow — and Dust is what pays for summoning and upgrading everything else in your collection.
Pick up the Portable Extractors early. They let you bank a Sprite without hiking to a fixed extraction point, which is the difference between keeping a Mythic pull and handing it to whoever third-parties you on the way there. Clear the daily challenges first, then go hunting with one in your pocket.
What to chase
The spawn boost covers rarity tiers rather than a featured list, so the sensible play is to open your tracker and hunt whatever Legendary and Mythic entries are still marked Missing. If everything at the top is already Collected, spend the day on levels and Dust instead — those two bonuses do not care what you are carrying.
The v42.10 update on September 3 added twenty-five Sprites in one go, so most collections still have plenty of gaps at the top of the list.
Tracking and trading them
Mark each Sprite Missing, Collected, or Mastered from the website or with slash commands in Discord — today is the day that third status actually starts moving. Anything you own can be offered in a trade with members of a Discord server you share, and duplicates out of the boosted spawns are exactly what the wanted ads are for.
Good luck out there, and update your Sprite Tracker once you've secured your new additions.
