Java Edition:Overstacked Striders
When striders were originally added they had a chance to have another strider riding them and that strider also had a chance to have yet another strider riding on them and so on. However, this was changed in 20w18a when only the original strider had the chance to have a passenger meaning the maximum stack size is two. Stacked mobs cannot enter portals until 1.21 Pre-Release 1, before then these mobs can only be in the Nether when obtained using this method.[1] Additionally, overstacked striders can be obtained in 22w13oneBlockAtATime by picking striders up in any dimension.
Obtaining
Spawning
From 20w13a to 20w17a, every strider has a 1 in 10 chance of having another strider on top of them, with that strider having the same chance. This allows for a strider to spawn with a theoretically infinite amount of striders riding it, however, the chances for a stacked strider to spawn gets very rare quickly.
Below is a list of the probability that a stack of at least the minimum size listed will spawn. The first 7 stack sizes are listed, it can continue infinitely getting 1/10 as likely for every additional strider.
| Stack Size | Probability |
|---|---|
| 1 | 1/1 |
| 2 | 1/10 |
| 3 | 1/100 |
| 4 | 1/1,000 |
| 5 | 1/10,000 |
| 6 | 1/100,000 |
| 7 | 1/1,000,000 |
22w13oneBlockAtATime Mob Wrestling
In the April Fools' version 22w13oneBlockAtATime, the player can pick up nearly any entity to create mob stacks in any combination. This powerful method also allows for overstacked striders to be obtained.
Usage
If you have a strider stack of 5 through 11, you can leash the bottom-most one and sit on the highest one. This will cause the player to ascend from the leash's elasticity, with the maximum speed being roughly 70 blocks per second with a strider stack of 11.
