Max Solo Setup Example:

Budget Solo Setup:

Yama's basic attacks cover all three combat styles, all of which can hit up to 46 without prayer.

• Melee - Yama swings his axe at his target. This is only used if the target is adjacent to him, and will hit everyone within three tiles of his main target. Activating Protect from Melee before the attack is used will block a majority of the damage, reducing its max hit to 6.
• Magic - Flames begin to envelop the player, after which Yama will snap his fingers to deal damage. Activating Protect from Magic before his fingers snap will fully protect the player.
• Ranged - Shadowy swirls begin to engulf the player, after which Yama will snap his fingers to deal damage. Activating Protect from Missiles before his fingers snap will fully protect the player.

Phase 1

• Red Glyphs of Fire indicating Yama will use a ranged attack first.
• Purple Glyphs of Shadow indicating Yama will use a magic attack first.

• The player doing so will take 2, 6, 9 or 12 damage upon stepping on a Glyph of Fire depending on how close Yama was to it when stepped on. 2 damage if Yama was four or more tiles away, 6 if three tiles, 9 if two tiles and 12 if one or adjacent to it.
• The Glyph of Shadow will drain 2-12 prayer points, and like the Glyph of Fire, drains more if Yama is closer to it.

Judge of Yama

Upon reaching roughly 66.6% and 33.3% of his health (not a hard cap), the first and second phases of the fight ends and an intermission phase will occur. Yama will teleport the players to pathways on the outside of the arena. Players are fully immune to any incoming attacks during the teleport, and any void flares that were present when this occurs are immediately destroyed without penalty.

The first player (instance creator) will always be placed west, while the second player will always be placed east.

Phase 2

Judge of Yama

Identical to the first Judge of Yama, reach and defeat it, then you'll be teleported back to the main arena for the final phase.

Phase 3

• Shadow Crash is a set of three fireballs in a line which fall upon the player. The side fireballs will spawn shadows after impact that converge toward where the center fireball landed (forming a bowtie shape). Yama will perform this attack three times, each one centered on the player at a cardinal, diagonal, and cardinal angle respectively.
• Getting caught in this attack will deal up to 20 damage per explosion. Players can dodge this by moving at least one tile from the center fireball perpendicular to the line. The fireballs are individual to each player.

Yama will still use his standard attack while the fireballs drop, so pray accordingly. Yama's first attack will depend on which glyphs were closest to the throne in the previous 2 phases and alternate every attack going forward.

• Yama will start with mage if the red fire glyphs were next to the throne.
• Yama will start with ranged if the purple shadow glyphs were next to the throne.

Yama can be offered contracts to drastically alter the fight. Acquisition contracts can only be acquired from a dossier, which Yama drops. The combat contracts for the purifying sigil can be acquired from both this dossier and via killing Yama's demons in the Chasm of Fire. Similar in function to awakener's orbs, these contracts are tradeable and are consumed upon attempting the fight. Some contracts are returned on successful completion of the fight.

Attacking any demon in the Chasm of Fire will cause a Green, Blue, Yellow, Red, or Purple sigil to appear over their head, indicating the preferred method Yama wants them to die. Satisfying this request, by using a specific weapon type for the killing blow, will double the drop chance of the contract associated with that weapon. Satisfying the yellow sigil via a special attack boosts the drop rate by 5x instead.
