Three account perks

Raid Discipline
Adds 10% to all Obsidian material chances from raid completions.

Guardian Resolve
Reduces all damage received from NPCs by 5%.

Melee Tempo
Halves standard melee attack delay against NPCs, rounded up with a 2-tick minimum. PvP and special attacks are excluded.
Raid Discipline adds 10% to Obsidian material roll chances at raid completion. Guardian Resolve supports survival. Use the Tempo perk that matches your main role.
Equipment upgrades to consider
Obsidian Life Spark
A successful weapon hit has a 20% chance to restore 1 Hitpoint.
Obsidian Spirit Siphon
A successful weapon hit has a 10% chance to restore 1 Prayer point.
Obsidian Aegis
Each non-zero NPC hit has a 1-in-12 chance to deal 25% less damage.
Prepare all combat switches and supplies required by your raid. Change Melee Tempo to Ranged Tempo or Arcane Tempo for a different primary role; the other two perks stay useful across styles.
A useful swap
For damage-focused clears, replace Raid Discipline with the matching Focus perk. For loot-focused completions, keep Raid Discipline and consider Boss Instinct in place of Tempo. These are trade-offs, not guaranteed faster or richer runs.

Before you spend
Check perk compatibility, compare permanent upgrades and review Forge materials. Socketed effects require worn matching gear; they cannot bypass the one-Tempo or one-Focus rules.
