Collectibles: What to Upgrade First

A phased plan for leveling relics — not a flat tier list. Start cheap, move to the universal top as it drops from events, then specialize by your hero's element. The two upgrade levers are kept separate below.

Level — enhancement energy (easy)

Costs only enhancement energy. The main, cheap lever — pour it freely into whatever you're prioritizing. Raises flat attack and the relic's bonuses.

Stars — relic shards (scarce)

Costs the relic's own shards, which are scarce. Save stars for the top relics only — that's where the elemental and crit special stats scale up. Don't waste shards on fodder.

Phase 0

Start — no top relics yet

Early on the jackpot boxes don't drop. Pour level-energy into the cheap q2/q3 relics you do get — they're first anyway, cheap, and give flat attack right away. Don't wait for q7, and don't spend shards yet.

As these drop from events, switch your level-energy here, and spend your first shards here too. They boost damage on any hero, regardless of element.
