Where gems go furthest, and where they're commonly wasted.
High-Value Gem Spends
- Hero Roulette targeted pulls — the most gem-efficient way to get a specific hero's shards, always in batches of 10
- Gilded Thread packs, timed with Hall of Governors — see Governor Gear Guide
- Speedups saved for a matching event (Strongest Governor, Armament Competition, Officer Project) rather than used on impulse
Lower-Value / Situational Spends
- Satin Thread packs — usually not worth buying since the Alliance Store provides a steady free supply (see Governor Gear Guide)
- Arcane Trove tiers past the free portion — compare pack price to actual return before buying (see Arcane Trove)
- Random gacha/chest pulls outside a targeted event — lower expected value than a planned Hero Roulette pull
The Core Principle
Almost every gem-spending mistake in this game comes down to spending outside the matching event window. Materials and speedups earn bonus value when spent during their matching event — spending them "whenever" instead of holding for that window is the single biggest silent gem-efficiency loss.
