⚔️ Auto-Attribute Swapping
Auto-Attribute Swapping exploits a longstanding vanilla Minecraft behavior (MC-28289) — when you switch hotbar slots in the same tick as an attack packet, the server reads damage from your new item but uses the cooldown that was already charged from your old one.
This mod automates the entire sequence at the packet level, invisibly, on every critical hit.
Crit conditions
The swap only activates when all of these are true:
- Falling (fall distance > 0)
- Airborne (not on ground)
- Not sprinting
- Not in water or lava
- Not on a ladder / vine
- No Blindness status effect
- Not riding a vehicle (horse, elytra, etc.)
