OSRS Grid Master Black Mask Guide | How to Get and Use It
The Black Mask in Grid Master gives you free extra damage right away without any questing. It’s one of the simplest early-game power spikes you can get and makes your melee hits stronger across most bosses and tasks.
How to Unlock the Black Mask
You don’t need to complete any quests for the Black Mask in Grid Master. Just teleport to the Tool Leprechaun on Harmony Island. From there, run north to the windmill. When you click the door, a safety check will trigger and teleport you straight to Mos Le’Harmless. That’s all you need to access the area and grab your mask.
Why It’s Worth Getting Early
Wearing the Black Mask increases your melee damage and accuracy against monsters that count as being on a Slayer task. Since the Slayer Master relic in Grid Master makes almost everything count as on-task, this bonus works nearly everywhere.
The damage boost stays active as long as you have the mask or a Slayer Helmet equipped. Once you get the Battlehat later, you can replace it since that item provides the same damage boost automatically.
How to Imbue the Black Mask
The mask starts with only the melee bonus active. To add the ranged and magic accuracy bonuses, you need to imbue it. Nightmare Zone is disabled in Grid Master, so you’ll have to use Soul Wars instead.
You can find Soul Wars games on World 666, where players usually rotate wins to farm points fast. It can take a few matches, but it’s the only way to imbue your mask in the event.
Combat Tips with the Black Mask
Always wear the mask during early Slayer and boss farming
Pair it with the Slayer Master relic for full task bonuses anywhere
Swap it out for the Battlehat later to keep the same effect permanently
Imbue it through Soul Wars to boost magic and ranged accuracy as well
Final Blurb
The Black Mask in Grid Master is one of the fastest ways to power up early combat. No quests, no grind, just teleport, grab it, and enjoy the bonus. With the Slayer Master relic active, it gives free extra damage across most of the game until you upgrade to the Battlehat.
