decaying winter yosef
Pending confirmation / 待确认: the supplied material does not support a complete guide.
The supplied field guide identifies Yosef as a final boss and associates his arrival with a heavily armoured-hostile warning. It places that appearance at wave 10 in its description. The current mode scope, health, attacks, phases, drops, and complete strategy are pending confirmation / 待确认.
Limits of the announcement reference
The guide describes the warning under AGENT-device voice lines. That provides context for recognizing an announcement, not a boss move list. No weapon, damage threshold, or guaranteed reward is inferred from the warning alone.
