Field Bosses and summoning scrolls

Field Bosses are server-backed shared targets. A summoning scroll places a target to fight; it does not grant permanent stats. Scroll stage determines the boss stage, and the scroll is consumed through the authoritative inventory flow.

The four scrolls are Rookie, Champion, Ultimate, and Mega. They are not bought or sold in the Market. You can craft the Rookie scroll, earn authored Tower scroll rewards, or obtain scrolls through supported reward sources; higher stages can be merged upward in the Workshop.

A Field Boss has its own position. Player reach is checked locally. Shared server activity and local fitness progression have separate ownership; the boss system does not upload raw health records to decide your permanent training gains.
