Bey Rivals parts are the pieces you combine into a bey in this Roblox spinning-top battler by BBR Productions: a layer, a disc and a driver, plus a launcher. The details below come from the developer's Discord patch notes, as recorded by fan trackers; the developer does not publish a parts table on Roblox, and we have not tested them ourselves. New here? Try the Bey Rivals beginner guide.
How Bey Rivals parts build a bey
- Layer: the bey itself. It sets the type, spin direction, number of blades, Burst Guard, passive, Awakening and moves.
- Disc: adds weight, stats and trait slots.
- Driver: the tip. It has stats and a type, and it decides your SPACE move.
- Launcher: a fourth part listed by the Paint Studio pass. How you get one and what it changes is not published.
Stats are graded SS to D for Attack, Defense and Stamina, next to Weight, Speed and Burst Guard. No full stat table exists, and Vector Valkyra is the only layer with a recorded grade (Attack SS). Parts also carry one of four types: Attack, Defense, Stamina or Balance.
Layers
A layer is the part you see spinning. Each has a type, a spin direction, a number of blades, a Burst Guard value, a passive, an Awakening and three moves on R, G and V. The second and third moves unlock as you level the layer. The game counts 30 layers and about 25 are named; the Bey Rivals beys hub lists them, and the Bey Rivals tier list ranks the strongest.
- Vector Valkyra: Attack starter with Rush Shoot, Flash Shoot and Jet Shoot. Its passive, Victory Rush, adds 20 percent burst damage.
- Halo Helios: a Mythic left-spin layer, Balance type since October 25, with the passive Helios Flare and the Awakening Spin Thief.
- Infernal Ifrit: an Epic Balance layer that steals spin on every hit, with Blazing Destruction, Inferno Smash and Blaze Step.
- Balder: a Defense layer sold in the Bey Shop. One tracker reports that its Awakening, Iron Spirit, stops bursting for the first 3 seconds.
Discs and drivers
Discs were retyped in the October 22, 2026 update, so older lists are out of date (see Bey Rivals updates). Current discs by type:
| Type | Discs |
|---|---|
| Attack | Nine, Triple, Aero |
| Defense | Jerk, Vertical, Yell |
| Stamina | Infinity, Heavy, Polish |
| Balance | Knuckle, Quarter |
Boost, Down, Upper and Magnum (Mythic) have also been seen; their types are not recorded.
Drivers change your SPACE move. The game has 21 drivers and about 16 are named: Variable (Common, Rush Dash), Xtreme (Mythic, Xtreme Dash charges straight at the rival), Liner (Wall Bank), Unite (Scrape Charge), Cycle (Rare), Assault (Epic), Yielding (Legendary), and Claw, Needle, Revolve, Weight, Trans, Impact, Quake, Press and Fusion.
Rarities, levels and stars
Parts come in six rarities: Common, Rare, Epic, Legendary, Mythic and Divine. Standard banner odds fall from 61.99 percent for Common to 0.01 percent for Divine, and the full table is on the Bey Rivals spin rates page. A patch can change a rarity: Kaiser Cerberon became Legendary on October 25.
Every part has a level, raised by merging duplicates, and stars, raised with duplicates or with BP. Max-star discs and drivers get 2 trait slots, and Mythic and Divine parts get 3. To fund upgrades, see how to get BP.
Bey Rivals parts: Exchange, Auto Sell and selling
- Exchange (added October 22) trades 3 parts of the same rarity for any one part of that rarity that you choose.
- Auto Sell (also October 22) lets you tick rarities from Common to Legendary on the Summon screen, and duplicates of those rarities sell the moment you pull them. It never sells shinies, Mythics, Divines or your first copy of a part.
- Selling refunds half of everything put into the part.
Use Exchange when you are missing one specific part and Auto Sell for spare low-rarity duplicates. Keep levelled parts out of the sell queue, since selling loses half of what you spent.
Shiny parts and Paint Studio
Mythic and Divine layers can roll Shiny. The Chaos Luck pass (99 Robux, permanent; see Bey Rivals game passes) makes every Mythic or Divine layer you summon 1.5 times more likely to come out Shiny. The base shiny chance is not published, and neither is whether a shiny layer plays differently from a normal one.
The Paint Studio pass (149 Robux, permanent) lets you paint your layer, disc, driver and launcher. It is cosmetic.
