OSRS Yama Contracts Guide: A Lucrative Money-Maker | Tons of XP Blog

Q: What are Yama Contracts?

Yama Contracts are tradeable items that allow you to fight a much harder version of the Yama boss. Each contract adds unique, difficult mechanics to the fight, but guarantees a specific, valuable reward upon a successful kill.

Q: How do you get Yama Contracts?

You can receive contracts as rare drops from killing demons within the Chasm of Fire on a Slayer task. They can also be obtained from the 'Dossier' unique drop from Yama himself, or simply bought from the Grand Exchange.

Q: Is fighting Yama with contracts profitable?

Yes, it can be extremely profitable. The guaranteed loot from a successful contract kill is often worth significantly more than the cost of the contract itself. For skilled players, this presents a high-risk, high-reward money-making method with hourly profits exceeding 10M GP.

Q: Can you use contracts in a duo?

It depends on the contract. The 'acquisition' contracts for resources (catalysts, worms, shards) can be done with a partner. However, the high-value contracts for Oathplate armour and Purifying Sigils must be completed solo.

Looking for consistent profit? Our guide to Yama Contracts explains how these tradeable items work, the guaranteed rewards, and the high-level money-making potential.

OSRS Yama Contracts Guide: A Lucrative Money-Making Method

While the standard Yama boss fight offers a chance at rare uniques, the real money is in the Yama Contracts. These tradeable items transform the encounter into a high-stakes challenge with a guaranteed, valuable payout for those skilled enough to succeed.

For high-level players, mastering these contracted fights is one of the most lucrative new money-making methods in Varlamore. This guide explains how they work and where the profit comes from.

What are Yama Contracts?

A contract is a consumable item that, when shown to Yama, initiates a special version of the fight. The contract is consumed upon starting the attempt.

Increased Difficulty: Each contract adds a set of difficult new mechanics or restrictions, making the fight significantly harder than the base encounter.
Guaranteed Reward: If you successfully defeat Yama under the terms of the contract, you will receive a guaranteed specific reward instead of rolling the normal drop table.
Risk vs. Reward: If you die during the attempt, the contract is lost, and you get nothing.

The Acquisition Contracts (Duo-able)

These contracts focus on gathering resources in bulk and can be completed with a partner, making them a popular choice for teams.

Contract of catalyst acquisition: Guarantees a large quantity of Aether catalysts.
Contract of worm acquisition: Guarantees a large quantity of Diabolic worms.
Contract of shard acquisition: Guarantees a large quantity of Oathplate shards.

The Strategy: High-level duos can purchase these contracts from the Grand Exchange, complete the challenging fight, and sell the guaranteed resource drop for a significant profit. The hourly profit can be immense, often exceeding 10M GP/hr for an efficient team.

The Solo Contracts (High-Value)

These contracts offer the most valuable rewards but must be completed alone, representing a true test of individual skill.

Contract of oathplate acquisition: Guarantees one of the three pieces of Oathplate armour. The profit from this contract is massive, as the value of the armour piece far exceeds the cost of the contract. This is a top-tier money-maker for elite solo players, with potential profits of over 15M GP/hr.
Sigil Contracts (e.g., Contract of forfeit breath): These five contracts reward the untradeable Purifying sigil pieces used to make Radiant Armour. While they don't provide direct profit, they are required for the cosmetic upgrade and are often completed by players for the prestige.

How to Get Contracts

Slayer: Killing demons in the Chasm of Fire can rarely drop contracts.
Yama Drops: The Dossier unique drop from Yama contains acquisition contracts.
Grand Exchange: The easiest way to get them is to buy them directly from other players.

Conclusion

Yama Contracts introduce a fantastic high-risk, high-reward system into OSRS bossing. They provide a clear path for skilled players to leverage their PvM abilities into consistent, top-tier profits. Instead of relying on the slim chance of a rare unique, contracts allow you to bet on your own skill for a guaranteed payday.
