Best Rule

Do Not Waste Early

If you are still deciding between weapon paths, saving fragments is usually better than spending them impulsively.

Use	Why It Matters	Priority
Weapon crafting	Often discussed alongside Yoru and other stronger progression weapons	High priority if you are following a sword-heavy endgame route.
High-end upgrades	Used as a premium material instead of a throwaway currency	Best saved for permanent account value.
Trading	Can carry player-to-player value when demand is high	Only smart if your own route does not need it soon.

Method	What It Gives You	Best Use
Dungeons	Repeatable clears and stable material routing	Best all-round answer for most accounts trying to farm consistently.
Treasure / bosses / world progression	Supplemental fragment chances	Useful when your route already overlaps with other target drops.
Trading	Player economy shortcut	Good if you have surplus value elsewhere and want to skip slower farming.
