Slayer Key Chest Rewards

This key does NOT have a change at saving if you are wearing a dragonstone set.

The Slayer Key Chest can be found just north of the Home Bank or accessed quickly with ::slayer. As you complete Slayer tasks, you'll collect Tier 1–4 Slayer Keys, which can be opened here for a variety of valuable rewards. Every key gives you a chance at rare loot, including the highly sought-after Corrupted Slayer Helm Kit.

How to Obtain Slayer Keys

Slayer Keys are earned as rare drops while completing Slayer assignments. The tier of key you receive depends on the Slayer Master that assigned your task.

Tier 1–3 Slayer Keys
- 1/60 drop rate from tasks assigned by Nieve, Konar, Chaeldar, Duradel, and Krystilia.
- 1/75 drop rate from tasks assigned by Turael, Vannaka, and Mazchna.
Tier 4 Slayer Keys
- Awarded exclusively while on Boss Slayer assignments received from Nomad.
- Drop at a rate of 1/35.

The higher the key tier, the better your chances of receiving some of the chest's rarest rewards.

Corrupted Slayer Helm Kit

One of the most prestigious rewards available from the Slayer Key Chest is the Corrupted Slayer Helm Kit. This cosmetic kit can be obtained from any tier of Slayer Key, although higher-tier keys offer significantly improved odds.

Slayer Key	Drop Rate
Tier 1	1 / 5,133
Tier 2	1 / 2,564
Tier 3	1 / 1,578
Tier 4	1 / 1,184 (improves to 1 / 1,100 when the Boss Reward Table is rolled)

If luck isn't on your side, the Corrupted Slayer Helm Kit can also be purchased from other players through trading.
