Masteries are upgraded versions of the unmastered glove that has a special buff. It will have 2-4 tasks ranging in difficulties. Which, more people have been grinding the mastery gloves over badge gloves.
Ultra Instinct Mastery
How to Unlock: Dodge a slap and slap them back 600 times
Dodge a slap 7 times in a row.
Ultra Instinct Mastery is one of the best masteries in the game. It is the only Paid mastery glove. It also is the only glove with only 2 Tasks. The ability is a 65% chance to avoid a slap, and E to teleport to a random location on the Main Island. Only downside is you can't do the "E" ability while rag dolled. 10/10
Wormhole Mastery
How to unlock: Teleport 1,200 times, Ambush 500 people, and Place 750 Wormholes.
Wormhole mastery is absolutely broken. Whenever you press the "R" button, it will immediately teleport you to your nearest wormhole. It also will have a longer speed boost duration after teleporting, and the final thing is you can place wormholes midair, which basically removes all placing restrictions which will be great. Only downside is you can't do the "R" ability while rag dolled. 9/10
Brick Mastery
How to unlock: Snipe 300 people, fling a brick at 200 Km, trip 1,000 people, and own the Brickmaster badge.
Master brick is not one of the target masteries you should go for first. It is a bit buggy as if you don't kick the brick fast enough, it can miss the target entirely! It is pretty cool though, and it is a dangerous combo with Master Cloud because whenever you drop a brick from that height it will always aim-bot to the nearest player! 5/10
Bus Mastery
How to Get: Slap 1,000 People, Own the "G-Grandson..?" Badge and hit people with the Bus ability 750 times.
Bus mastery is one of the better masteries. It gives you the perk of not hitting yourself with your own bus. It also gives you an "omnidirectional" bus, which basically means the bus can spawn from anywhere not just north of the map. And it does give the Bus ride ability, which squishes the ran over players and slows them for a couple of seconds, which you can use to use the "Accident" ability and run them over. 9/10
Obby Mastery
How to get: Slap 1,000 people, kill 500 people with kill bricks, and place 2,000 obby parts.
Obby is a building mastery, and once you get some other masteries like glovel, you won't really use the Obby glove anymore, because the buffs are just the obby placing, which is ehhh. So honestly, only go for this one once you get every other one. 6/10
Glovel Mastery
How to unlock: Dig 350 times, Land 1,000 critical strikes, and land 20 critical strikes in a row
Glovel is one of the best Masteries in the game. The critical strikes go much further, you can dig into the ground in about a second, and the Market Gardening launches you realy far in the air to land somewhere else. 10/10
Cloud Mastery
How to Unlock: Spend 200 Minutes in the sky, kill 50 people from jumping above, and travel 200,000 studs in the cloud.
Cloud is the easiest mastery to get and is one of the funniest with the combos you can do with it. It isn't one of the best masteries, but whenever someone steals your cloud, you can bomb them out of it. It's just a nice buff and is fun to use. 8/10
Killstreak Mastery
How to Unlock: Steal 100 total kills from other players, kill 1,000 players or no kill killstreak players, Reach phase 100.'
Killstreak mastery is very mid. It does make it easier to get more kills with the fact you start with one, and the Killbank makes it easier, as you can Save 10 kills before going to 75. But overall, it's not one you should be going for first as it is very grindy.
