FYI, i also hacked my movement speed to be super speed (just yourself). key hint, when u use Grant, and use the ability to mark for death, and you kill the target, ur movement speed is +20%. this translate to exactly 1.200000048 (dont ask me why) in FLOAT. and then back to 1.000000 after 7 seconds.
now to find the value for fast fire rate and melee rate.... and invisibility for sound
