Requirements

Access and practical preparation

A Kingdom Divided

Complete the quest, speak to Yama in person and sign the Voice of Yama's contract in Yama's Domain.

Melee or Magic plan

Choose a coherent primary method. Both styles are viable, but a two-style switch is not a hard requirement.

Demonbane equipment

Emberlight and Purging staff are strong optional upgrades after While Guthix Sleeps.

Solo or duo plan

Choose supplies and movement roles for the selected team size before challenging Yama.

Core mechanics

What controls the encounter

P

Prayer-reactive attacks

Protect from Melee against the axe swing, Protect from Magic before the flame snap and Protect from Missiles before the shadow snap.

High
G

Fire and shadow glyphs

Stand on the matching glyph before its special resolves; only one player needs to activate it in a duo.

High
W

Waves and fire streaks

Skip over shadow waves and keep moving through fire streaks so they do not disable prayer or bind you away from the next glyph.

High
P3

Final phase

Track the faster attack and special sequence while preserving a clear path to the required glyph.

Strategy

A practical step-by-step plan

1

Choose the combat plan

Use a coherent melee or Magic setup and decide solo or duo roles before signing the contract.

2

Read the snap attack

Match Protect from Magic to flames and Protect from Missiles to shadow swirls; use Protect from Melee for an adjacent axe swing.

3

Claim the correct glyph

Step onto the fire or shadow glyph that matches the incoming special, with one player handling each activation in a duo.

4

Cross the moving hazards

Skip over shadow waves and keep running through fire streaks so prayer stays active and the next glyph remains reachable.

5

Preserve the final route

Enter the last phase with Prayer, poison control and open tiles rather than spending every supply on earlier damage.

What should I upgrade next?

Method-specific progression priorities

1

Arclight → Emberlight

Improve the melee demonbane weapon first so the melee damage role reaches its final practical weapon without an unnecessary later repeat.

Major upgrade
2

Trident of the swamp → Purging staff

Upgrade the Magic role separately so both required combat styles have a purpose-built weapon.

Major upgrade
3

Virtus robe top and robe bottom → Ancestral robe top and robe bottom

Treat the Magic armour step as a later damage upgrade after Emberlight, Purging staff and clean phase switches are already in place.

Minor upgrade
Upgrade ROIEnter upgrade values to calculate

Common mistakes

Avoidable causes of failed or inefficient trips

Entering without a complete two-style setup

Stacking with a duo partner during hazards

Prioritizing damage over arena awareness
