Old School RuneScape
Early, mid, and late are rooms, not a promise. Rates move. Wiki keeps the hour. A paid coach is a call, not this page.
Levels
Early
1–30. Quests skip a painful chunk if you run Tourist Trap and The Grand Tree. After that Draynor and Varrock rooftops teach the click. Fail less, not faster. Marks of grace are why rooftops beat a random dungeon at this level. Summer pie is a boost, not a personality.
Mid
The live training page still ranks Brimhaven Arena and then the Wilderness course as the fast mid rooms — both cost attention and, in the wildy, a bag. Rooftops from Canifis through Seers are the honest mid if you want marks and a calmer hour. Seers with the diary teleport is a real course, not flavour.
Late
62+ Hallowed Sepulchre is the fast room after Sins of the Father. Stamina, a private instance if you have it, and the floors you can actually clear. Ardougne rooftop remains the rooftop people finish 99 on. Rellekka is slower and quieter. Confirm rates on the wiki. They move.
Wear
Graceful. Stamina. Light boots and a spotted cape if you still run the wildy course. Food for fails. Sepulchre wants hitpoints and a brain, not a max melee set. Karamja gloves matter in the Arena. Weight is the mechanic.
Afk
Rooftops you fail less. Afk agility is a lie past the first two courses. The click is the skill.
Fast
Arena or Wilderness mid, Sepulchre late, as the live page still ranks them. Tickets and coffins are the side loot. Do not invent a third dungeon.
Watch
Marks slow down when you out-level a rooftop by twenty. A course you fail is not efficient. Wildy course is PvP adjacent. Protect item.
