Saros guide: Halcyon explained and Halcyon locations in Saros

Halcyon is a key upgrade material in Saros used to unlock skill tree nodes and progress character builds.

Players can find it in containers, side rooms, ground loot, Alpha enemy drops, and some repeatable activities.

Its spawns are limited and partly random, so farming routes are useful for steady progress.

Knowing where Halcyon appears helps players collect upgrades faster and complete builds sooner.
