OSRS Grandmaster Combat Achievements: The Ultimate PvM Challenge

Welcome to the apex predator tier of Old School RuneScape's Combat Achievements: Grandmaster. This is not merely a tier; it's the culmination of mastering virtually every high-level PvM encounter the game has to offer. Achieving Grandmaster requires completing every single task across all tiers, demanding absolute perfection, strategic depth, top-tier gear, and immense dedication. Each Grandmaster task itself awards 6 points, contributing to the maximum total (2470 points based on data).

This guide assumes familiarity with all previous tiers. Refer back if needed: Easy, Medium, Hard, Elite, Master, and the main Combat Achievements Overview.

Grandmaster Tier Requirements

Only the absolute best need apply:

  • Skills: Maxed combat stats (99 Attack, Strength, Defence, Ranged, Magic, Hitpoints, Prayer) are practically mandatory. Maxed Slayer (99) required for some bosses.
  • Items: The absolute best-in-slot gear for multiple combat styles is required. Specific items noted: Dharok's Greataxe (or thralls), Salamander. Brittle key. Avernic Defender needed to create Ghommal's Avernic Defender 6.
  • Quests: All PvM relevant quests completed, including While Guthix Sleeps for Tormented Demons (if applicable based on TD task placement in final list). All prerequisites from lower tiers apply.
  • Skill & Knowledge: Flawless understanding and execution of mechanics for Inferno, CoX CM, ToB HM, ToA Expert (high invocation), Nex, Nightmare, DT2 bosses (including Awakened variants), Fortis Colosseum, and more.
