Velocity
Modifies knockback you receive from attacks
There are multiples modes of Velocity that all work differently, some are ghost and some are very detected, please read the anticheat safety article for more information.
Jump Reset Ghost
Jumps after you take damage to legitimately reduce your knockback.

Chance %
How often you jump reset after taking knockback
Timing (ms)
How long after you've taken knockback before you jump
Delay Ghost
Increases your ping so you can still move and attack while you've taken knockback by delaying it, meaning if someone hits you in a fight you can still hit them while your knockback has been delayed.

Ground delay (ms)
Delay before reacting while on ground
Air delay (ms)
Delay before reacting while in air
Reduce
