Jade Sword or Strange Mask first?
Treat the mask chamber as both a puzzle stop and an ambush. If the squad is weak, collect the tablet while preserving an escape route and delay the mask pickup. The Jade Sword door is the structured objective; the Strange Mask is optional utility with an immediate risk. A team that can safely manage the plate may take both, while a low-health solo player should prioritize leaving alive with progress.
After the door opens, the Jade Sword can support later combat through its reanimation effect, while the mask can turn one chosen defeated enemy into a temporary ally. Neither reward compensates for an empty furnace or an unprotected carrier.
