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
Turael only to unlock the skill and finish a streak you intend to break. Mazchna and Vannaka are the first real lists. Buy the helm as soon as it exists. Broad bolts and a cannon unlock are the mid-early purchases that actually pay. Block list starts empty on purpose — you do not know your hates yet.
Mid
Chaeldar through Nieve or Steve. Cannon every task the assignment allows. Burst the dusts and the nechryael when the level and the spellbook are there. Konar is brimstone and a location lock. Take her when you want the chest, not when you want the fastest 99.
Late
Duradel. Skip list on the wiki. Burst and barrage the assignments that still say so. Boss tasks are Bosses pages, not a training paragraph. 99 Slayer is a skip sheet and a prayer, not a secret monster.
Wear
Slayer helm on task. The combat style the monster is weak to. Face cover the bestiary already named — nose peg, earmuffs, witchwood, elemental shield. Cannon in the rooms that allow it. Protect the prayer that matches the hit.
Afk
The task you can cannon or leave on a crab-like monster. Afk slayer still needs a check on the timer.
Fast
Burst and barrage assignments. Skip what the live page skips. Do not farm a slow task because a streamer liked the drop table in 2019.
Watch
Wrong helm. Wrong prayer. Bare-faced spectre. That is the wipe. The monster page owns the finish mechanic.
