Notes

It requires 56 Slayer to kill, with 153 Slayer experience being rewarded. Ranged attack hits quickly. If you wear Earmuffs whilst fighting warped terrorbirds ranged damage will be reduced according to the slayer masters.

Tactics

You will need to use the Crystal Chime on them to damage them. This effect will disappear shortly. They are light grey when invincible and grey-green when vulnerable. If more than one is attack with you Range, it's recommended that you turn on Range pray for some seconds, that will stop them attempting to attack you with Range. And they will try to get near you to attack with Melee. But in most cases they get stuck before reaching you.

Examine

You don't think you can harm this terrorbird.
This bird looks a little more vulnerable now.
