Vault Keys
Every drop you hold is a key. Keys can substitute for tokens you’re missing toward a vault’s requirements — a higher-tier key covers more ground than a lower-tier one.
Key Substitution Rules
Section titled “Key Substitution Rules”| Key tier | Substitutes for |
|---|---|
| Mythic | Any token in any vault |
| Legendary | Legendary, Epic, Rare, or Common tokens |
| Epic | Epic, Rare, or Common tokens |
| Rare | Rare or Common tokens |
| Common | Common tokens only |
Your own key inventory — which keys you hold, when you obtained them, and whether each has already been used — changes continuously; see the live Vault Keys for your current inventory. This page covers the mechanism, not a point-in-time snapshot of it.
