Bullseye quick answer

Bullseye asks you to kill a regular boss with a stone. Do it on a dedicated attempt; it is easy to kill the boss normally before the stone setup is ready.

A June 6, 2026 developer reply reinforces the same route logic by calling Bullseye a strong Stoner pairing when the setup is ready, and a fresh late-June player clear now shows Stoner plus Bullseye/Chosen can comfortably carry Pressure 12 when the run is built around it.

Keep movement and survival online first, then lower the boss into a safe throw window.
