Legacy Piece Gems — Stat Rolls, Sockets and Set Bonuses
The gem system is where a finished build gets its last few percent. Because the board publishes both the roll range and the drop weight for every tier, you can work out whether re-rolling a gem is worth the shards before you spend them.
Trello board pulled:
Gem tiers
| Gem | Stat roll range | Drop weight | Sell value | Full-slot bonus |
|---|---|---|---|---|
| Common Gem | 0.5–1% per stat | 40% of gem drops | 10 Shards | +0% to that type's DMG |
| Rare Gem | 1–2% per stat | 30% of gem drops | 50 Shards | +2% to that type's DMG |
| Epic Gem | 2–3.5% per stat | 18% of gem drops | 100 Shards | +4% to that type's DMG |
| Legendary Gem | 3.5–5% per stat | 8% of gem drops | 350 Shards | +6% to that type's DMG |
| Mythic Gem | 5–8% per stat | 4% of gem drops | 1000 Shards | +10% to that type's DMG |

Should you sell your spare gems?
Each tier has a published shard sell value, so spare gems are a Shard income rather than clutter — and Shards buy chests in the Material Shop. The exception is any gem that rolled near the top of its range on a stat your build actually uses: those are worth more socketed than sold, because re-rolling into the same result costs more than the sale returns.
