Attacking another player with Killaura and Criticals. Notice how the crosshair is not pointing at the target, yet the attacks are still hitting it.

Getting attacked by another player with Killaura. From this perspective, it looks like the attacker is facing the target. This prevents other players from seeing that Killaura is being used.

Killaura is a hack that automatically attacks entities around the player.

Killaura faces its target on the server-side, but not on the client-side. This allows the user too look around freely while still preventing other players and server plugins from seeing that Killaura is being used. (See the pictures on the right for a demonstration of this effect.)

When checked, the “Use Attack Cooldown as Speed” checkbox disables the “Speed” slider and instead dynamically calculates the speed based on the attack cooldown, such that each attack will deal the full possible damage.

In Wurst 7, Killaura's speed is always calculated dynamically based on the attack cooldown.

In Wurst 6, when the “Use Attack Cooldown as Speed” checkbox is not checked, the “Speed” slider determines how many times per second Killaura will try to attack the target¹⁾.

The “FOV” slider limits how far Killaura will move the player's head in order to face and then attack an entity. Any entity that is outside of this field of view will not be attacked at all.

The FOV generally goes “both ways around”: An FOV setting of 180° will attack any entities that are up to 90° away in any direction, resulting a 180° cone centered around where the player is facing. Similarly, an FOV setting of 90° creates a 90° cone where anything up to 45° away can be attacked, and so on. An FOV setting of 360° will attack targets all around the player.

The FOV setting takes both horizontal and vertical rotation into account and is always based on the player's client-side facing.

When checked, Killaura will only attack if the player has line-of-sight to the target. This helps with bypassing AntiCheat plugins but can sometimes cause problems when the target is behind tall grass or similar blocks.

A value of 0 disables this filter.

Filter end crystals
Type	Checkbox
In-game description	“Won't attack end crystals.”
Default value	not checked
Supported Minecraft versions	1.16.3, 1.16.2, 1.16.1, 1.15.2, 1.14.4 (since Wurst 7.5) 1.12 - 1.12.2, 1.8 - 1.8.9 (since Wurst 6.34)

When this checkbox is unchecked (as it is by default), Killaura will attack end crystals.

Some other clients create a separate “CrystalAura” or “AutoCrystal” hack to get this functionality, but Wurst doesn't need to do this because its settings are powerful enough to integrate CrystalAura functionality into Killaura itself.

When the Priority setting is set to “Health”, Killaura will attack all other entities in range before attacking end crystals. This is not the case when Priority is set to “Angle” or “Distance”.
