Hi,
I am guessing you are talking about Rahyeh (the void bird god) and his infamous “pizza”.
Nothing has changed.
You need to adjust how far from him you are running according to your mouvement speed. The further away the longer the distance is so the faster you need to be.
If you feel you are too slow go closer, if you feel you are to fast try further
The higher your movement speed the further out you need to be to not get hit as Rahyeh’s attack has a constant angular velocity which you need to match.
