Velocity
Velocity reduces or removes the knockback the player receives from attacks, projectiles, and explosions. Configurable as a percentage: 100% is vanilla knockback, 0% is no knockback at all. On servers with strict movement validation, Velocity is one of the most commonly flagged combat modules.

What it does
Velocity modifies the knockback vector the client applies when the server sends a velocity update. The client receives the knockback packet but applies a scaled-down version. Configurable options:
- Horizontal — X and Z axis knockback percentage.
- Vertical — Y axis knockback percentage.
- Explosion — separate percentage for explosion knockback.
- Source filter — apply only to melee, only to projectiles, or all sources.

| Aristois | Yes | Standalone client implementation |
Server compatibility
- Hypixel — Restricted. Server-side velocity validation detects reduced knockback immediately.
- 2b2t — Permitted. No anti-cheat active.
- CubeCraft — Restricted. Sentinel validates client position after velocity packets.
Detection behavior
Velocity is one of the easiest modules to detect because the server has a record of the velocity it sent. Anti-cheat checks:
- Position delta after velocity. The client position after knockback does not match the expected trajectory.
- Repeated inconsistency. A single lag spike may explain one anomaly; consistent deviation is flagged.
- Correlation with combat. Reduced knockback immediately after taking a hit.
Velocity above 80% is less obvious than full 0% knockback. On servers with modern anti-cheat, even moderate Velocity produces a detectable signature.
Known limitations
- Server lag can produce legitimate-looking velocity inconsistency, which some anti-cheat systems tolerate.
- Explosion velocity is checked differently from melee velocity on some servers.
- Combined with KillAura and Criticals, Velocity amplifies the overall detection signature.
