What should I upgrade next?

Method-specific progression priorities

1

Abyssal bludgeon → Inquisitor's mace with Avernic defender

Improve the primary style first so prayer cues resolves with fewer switches.

Major upgrade
2

Complete the recommended style set: Inquisitor's mace with Avernic defender + Bandos chestplate and Bandos tassets + Sanguinesti staff

Add the remaining combat-style switches once spawn control can be handled without losing position.

Moderate upgrade
3

Scythe of vitur

Complete the The Nightmare high-end set only after every required combat style has a reliable weapon.

Minor upgrade

Common mistakes

Avoidable causes of failed or inefficient trips

Losing position during spawn control

Mishandling team positioning: Spread cleanly so one mistake does not disrupt the group.
