Legacy Piece Quests — All Objectives and Rewards

Sorted by type below, with the objective exactly as the game counts it — "Kill 2000 NPCs" means any NPC, while "Defeat Flashy Flash with Combat Style" checks which style you have equipped when the kill lands. Several quests fail quietly because of that second kind of condition.

Quests worth doing first

The kill-count dailies (100 enemies, 20 bosses, 2,000 NPCs) complete themselves while you farm materials, so they are free EXP if you claim them. The style-locked ones are the trap: keep the Combat style equipped for a session and clear all of them in one go rather than re-equipping every time one appears. Trial quests — Cursed Child Trial, the Fire Force line — gate specific weapon unlocks and are best attempted after your rank is comfortably above the boss they point at.
