What it does
FastXP fires Bottles o' Enchanting in a stream, one per tick instead of the vanilla pace. With Mending that means repairing armour and weapons in a couple of seconds, right in the middle of a fight.
Its main stage is anarchy crystal PvP and long survival fights: while the opponent retreats to mend their gear, the cheater repairs on the spot and keeps pushing. The bottles often go straight down at the feet even though the player is looking at the opponent. Fights lose their natural pauses, and an honest player keeps running into armour they can't break in time.
How to spot it
- A cloud of bottles and experience orbs at the player's feet — dozens within seconds
- Mending armour goes back to full almost instantly, mid-fight
- Bottles fly downward while the player looks ahead or at an enemy
- The slot flicks to the bottles and straight back to the sword
How it gets caught
Holding the button leaves a pause between throws, and manual clicking has an uneven rhythm. FastXP throws in an even stream faster than that pause, sometimes several throws in one tick. The second clue is direction: the throw packet carries a rotation, and a throw at the feet while looking at an opponent doesn't match what the player sees. The third is a slot that switches to the bottles for exactly the length of the burst.
A connection hiccup bunches throws together, so the series is judged as a whole: pace, slot and direction together, over many bursts.
