Yama’s Contracts – OSRS

Contracts

Yama can be offered contracts to alter the nature of the fight. Resource/material contracts can only be acquired from a dossier, which Yama uncommonly drops. The combat contracts for the purifying sigil can be acquired from both this dossier and killing Yama’s demons in various manners. Similar in function to awakener’s orbs, these contracts are tradeable and are consumed upon attempting the fight.

Refer to Yama/Strategies § Contracts for additional details on contracted fights.

There are several contracts which modify the fight to some degree:

Some of these contracts have a difficulty comparable to that of the awakened variants of the post-quest Desert Treasure II bosses, and defeating Yama with these contracts will grant the player with purifying sigil pieces, which are used to grant the ability to use Radiant Oathplate armour, which is white in colour. Apart from Yama’s stats being adjusted, these contracted fights add or modify existing mechanics from the original fight.

The resource and pet contracts allow two players to challenge Yama, as long as one of these two players has the contract to show him. The equipment and sigil contracts can only be completed alone. If Yama is defeated after being shown the sigil or pet contracts, the player will be refunded the contract. Unlike the awakened Desert Treasure II bosses, successfully completed contracted fights are not tracked separately.
