OSRS Grid Master Masteries Guide | All Combat Upgrades

Combat Masteries are where your Grid Master power really starts to snowball. Each tier you unlock boosts all three combat styles, stacking damage, healing, and defense into permanent upgrades. By the final tier, you’re basically a raid boss in your own right.

How to Unlock Masteries

Combat Masteries unlock as you finish key milestone tasks on your grid. Every major completion powers up Melee, Ranged, and Magic together, no more style-specific grinds like in past leagues.

You’ll start seeing Mastery unlocks as soon as you clear a few bosses and grid objectives. Each one stacks passively for the rest of the event.

Combat Mastery Tiers and Effects

Each tier adds a new passive buff along with unique bonuses to Melee, Ranged, and Magic. Once a tier is unlocked, the effects stay active permanently.

Tier 2

Passive: All healing increased by 20 percent.

Melee II: 10 percent chance to trigger an echo hit for half your max hit (PvM only).

Why Combat Masteries Are Epic

Each tier is a direct multiplier on your entire account. Accuracy doubles, healing scales off damage, and your attack speeds drop into absurd territory. The Tier 6 passives make every style capable of wiping bosses in seconds, especially when combined with relics like Golden God or Combatant links.

Final Blurb

Combat Masteries are the single biggest jump in power you’ll feel during Grid Master. Every tier stacks, every style benefits, and the late-game bonuses break combat wide open. Hit Tier 6 and you’ll be watching bosses like Branda and KQ melt before you can even swap prayers.
