Keys open optional reward rooms inside dungeon runs
Current gameplay shows gated side rooms requiring specific key tiers, including Silver, Gold and Platinum examples. These rooms sit off the main clear path and can contain higher-value chests or materials.
The most useful rule is simple: do not spend a rare key automatically just because a gate appears. If you are already overgeared for the current difficulty, saving it for a harder run may be more valuable.
Key decision checklist
Use the key now when:
- The current run is at a difficulty where the extra chest can meaningfully upgrade you.
- The gate clearly matches the key you have.
- You are not risking the run just to reach the room.
Consider saving it when:
- You are speed-leveling through content you already outscale.
- The current difficulty is producing gear you replace immediately.
- You do not know whether the key is rarer than the room reward.
What to expect from locked rooms
Locked rooms are optional reward detours, so their value depends on the difficulty, your current gear, and the key you spend. Save rarer keys when a higher-difficulty run could turn that extra chest into a meaningful upgrade.
