Quick answer
Lower a normal creature's health, create space, complete one full rotation, then land the killing shot without using the scope. The target must die from that final shot.
Choose a forgiving target
Practice on an isolated ordinary creature that can survive until the planned finishing shot. Boss movement and large health pools make it harder to identify which condition failed.
Make every input deliberate
- Lower the target to a predictable finishing range.
- Create enough space to rotate without hitting terrain.
- Complete a full 360-degree turn.
- Do not scope the finishing shot.
- Confirm that the shot, not a delayed hazard, caused the kill.
If it does not unlock
- Check that the rotation completed before firing.
- Check that the killing shot was unscoped.
- Check that another player or environmental effect did not finish the target.
- Retry on a normal creature with a cleaner setup.
Build consistent inputs with Trick Shots and Killscore.
