After hooking a Survivor, THWACK! activates:

The next time you break a Breakable Wall or a Pallet, all Survivors within 28/30/32 meters of your location will scream and reveal their Aura for 4 seconds.

Your basic attacks make Survivors drop their item on impact.  While on the ground, it takes up to 90 seconds for the item to lose all of its charges if it is not picked up.  Reveal items on the ground within 32 meters with a white aura.  The aura will slowly fade to red until the item is empty of charges.

When a Survivor is rescued from a hook at least 24 meters away, Devour Hope receives a token.

2 Tokens: Gain a 5percent Haste status effect, 10 seconds after hooking a Survivor, for a duration of 10 seconds.

3 Tokens: Survivors suffer from the Exposed status effect.

5 Tokens; Grants the ability to kill Survivors by your own hand.

The Hex effects persists as long as the related Hex Totem is standing.

Your base Terror Radius is increased by 8 meters.

Whenever you are outside of a Chase, your Terror Radius is reduced by 16 metres while your Field of View is increased by 3/5/10 °.
Field of View gains do not stack.

After damaging a generator, its aura is highlighted in yellow.

Whenever a Survivor enters the dying state, every affected generator explodes, losing 10percent worth of progress, and starts to regress.

Any Survivor repairing a generator when it explodes will scream and reveal their aura for 12 seconds.

Eruption has a cooldown of 30 seconds.

Survivors within your Terror Radius have a 50percent penalty to healing progression speed, and healing Skill Checks move 50percent faster.
