HeadShot Magnet is one of those features that sounds gimmicky until you actually use it tuned correctly. With Aboki Rage Bait, you get two parameters: Power and Hold Time.
Power
How aggressively your aim biases upward toward the head. Start at 25 and bump up by 5 until you notice the bias in clips. Above 60 it starts to look unnatural — keep it subtle.
Hold Time
How long the bias persists after the initial engagement. Snipers want short hold time (snap to head, then release). Burst rifles want longer hold time (so multiple bullets land in the head).
Combine with iTrack
HeadShot Magnet pulls up. iTrack handles lateral strafe. When you combine them, an enemy strafing left to right at head height becomes a free kill.
Disable it on shotguns
Headshot bias is pointless on shotguns — the pellets spread wide. Use the Quick Toggle to turn HeadShot Magnet off when you swap.
