Microgrind: learn the mechanics the game never explains

Plain-English guides to the Old School RuneScape mechanics new players get wrong: why a click lands a tick late, how safespots and flinching keep a monster from hitting back, and why protection only matters on the tick a hit lands (the skill behind prayer flicking). Each guide comes with a free browser drill to practise it, with instant feedback, a daily challenge and leaderboards where every ranked run is replayed on the server before it counts.

Guides

• Leash flinching: resetting a monster by leaving its territory
• 3-tick and 2-tick rhythm: the timing behind tick manipulation
