Roblox Rush

The Roblox Rush is an advanced technique discovered and named by Tytaneum that allows Steve to utilize new movement approaches. There are many ways to activate a Roblox Rush, but the general requirements for the technique is that steve must attack an entity while pushing into an Anvil. If done successfully, Steve will be rewarded with a large horizontal burst of movement in which he is fully actionable and can surprise opponents. The easiest way to achieve these conditions is by dropping an anvil next to the crafting table, as the crafting table counts as an entity. Steve can either burst forwards or backwards depending on his position relative to the anvil as well as the direction he is holding. The Roblox Rush is likely a byproduct of a strange interaction between hitlag and the anvil's collision box, causing the anvil to eject steve once the hitlag ends.

There also exists an alternate version of the Roblox Rush that may be achieved by simply running into a grounded anvil and quickly rolling backwards, significantly boosting the distance which Steve rolls.

Timing

The move uses up one unit of iron, out of three Steve starts each stock with, and a maximum of 100 units shared with dirt, wood, and stone. It fails if used with no iron left, or if an anvil from a previous use is still active.

Attack (success)

The timings below are when the anvil does not land on the ground. The move resets Steve's horizontal momentum when initiated, then causes him to stand on top of the anvil when it is generated, which falls straight down using its own physics. Steve is considered to be grounded while on the anvil, and can perform grounded actions on it after the animation fully plays out; he can also use it to restore his air dodge or double jump, but the latter only if he does not jump cancel the move.
