Key chests
| Details | |
|---|---|
| Feature type | Key-based reward chests |
| Access | Open or unlock a supported chest |
| Rules and progression | |
| Requirements | Matching keys in inventory |
| Effects | Batch opening; eligible key saving; reward overflow to bank |
| Limits | 1–40 openings per click, depending on total donated |
Key chests consume matching keys for rewards. Supported chests can process several openings in one click, depending on your total donated amount. Carry the keys in your inventory and use the chest's open or unlock action.
Supported chests
| Chest | Key and opening rules |
|---|---|
| Crystal chest | Crystal key. A complete dragonstone armour set gives a separate 15% key-saving chance. |
| Enhanced Crystal chest | Enhanced crystal key. If you have none, an ordinary crystal key uses the ordinary Crystal chest rewards. The complete dragonstone armour set can also save enhanced keys. |
| Slayer chest | Tier 1–4 Slayer keys. The highest remaining tier is used first: Tier 4, then 3, 2 and 1. |
| Brimstone chests | Brimstone keys. Both supported Brimstone chest variants use batch opening. |
| Grubby chest | Grubby keys. Batch opening applies, but this chest does not use the donator key-saving roll. |
| Larran's chest | Larran's keys. Its usual Wilderness setting and reward rules still apply. |
Each successful opening awards its reward even when the key is saved. A saved key remains available for another opening. The chest does not need to consume a key for that opening to count.
Openings per click
The limit uses total donated. Each click makes at most the number of matching keys you carried at its start or your batch limit, whichever is lower. Click again to use keys left over after the batch.
| Total donated | Maximum openings per click |
|---|---|
| Below $10 | 1 |
| $10 | 5 |
| $50 | 10 |
| $100 | 15 |
| $250 | 20 |
| $500 | 25 |
| $1,000 | 30 |
| $2,500 | 35 |
| $5,000 or more | 40 |
Each row applies until the next threshold. For Slayer chests, the starting count combines all four key tiers.
Saving keys
The donator key-saving roll uses your current rank. It applies to Crystal, Enhanced Crystal, Slayer, Brimstone and Larran's chests.
| Donator rank | Key-saving chance per opening |
|---|---|
| Donator | 2% |
| Super Donator | 5% |
| Elite Donator | 8% |
| Noble Donator | 10% |
| Gold Donator | 12% |
| Platinum Donator | 15% |
| Legendary Donator | 18% |
| Supreme Donator | 20% |
A complete dragonstone armour set checks its own 15% save first at Crystal and Enhanced Crystal chests. If it does not save the key, the donator roll still applies. These percentages are separate checks, rather than values added together.
Receiving rewards
Rewards normally enter your inventory. On this route, overflow is sent to your personal bank; anything the bank cannot accept drops at your feet. Check both destinations and the ground before leaving.
At $500 or more total donated, Crystal chest rewards go directly to the bank. Enhanced Crystal chest item rewards use that direct-bank rule too; its coin reward starts in inventory. This direct-bank route does not use the inventory overflow fallback. Leave bank space before opening large batches.
See Reward boxes and caskets for portable containers, which can have different delivery rules.
