The Booster Glove in Slap Battles just got a massive upgrade with its brand-new Mastery system, and trust me—it’s worth grinding for. Once you complete the mastery challenge, you unlock upgraded boosters that pack serious speed and style. If you’re ready to take your gameplay to the skies (literally), here’s exactly how to do it.
Booster Mastery is a progress-based reward system added in a recent update. Once completed, your Booster Glove receives visual upgrades and enhanced functionality—like jet engine flames, nuclear boosts, and other powerful effects.
How To Unlock Booster Glove Mastery
Objective:
Attach 2 Boosters to 750 different players
Yes, you read that right—750 players. But don’t worry, it’s not as impossible as it sounds.
Step 1: Equip the Booster Glove
Make sure you have the Booster Glove unlocked. Head to the glove selection area and choose it before entering the arena.
Step 2: Press E Near Other Players
Once you’re in the arena, press E to activate your boosters while near other players. If two boosters attach to a player, that counts toward your total.
Tip: You can attach boosters by just dashing near or into other players with the ability active.
Step 3: Rinse and Repeat
Keep doing this every match. You’ll need to successfully attach boosters to 750 different players. This is not 750 uses, but 750 unique connections.
Pro Tips To Speed Up the Process
Play on Full Servers – More players = more targets.
Use Public Servers – It helps ensure you’re hitting a variety of players, not the same ones.
Don’t Eliminate Too Fast – Give yourself time to attach boosters before knocking players off the map.
Use Shift Lock – Helps with precision when dashing around players.
Track Progress – There’s usually a mastery progress tracker in your glove menu (depending on the update).
