OSRS Boss Progression Roadmap: What to Kill at Every Combat Level

Old School RuneScape has some of the most punishing—and rewarding—boss fights in any MMORPG. But unlike modern games that hand-hold you through a linear storyline, OSRS drops you into a massive open world with dozens of bosses and almost no guidance on which ones you should actually fight at your current level. If you've ever asked yourself: "I have 70 Attack—now what? Where do I even start with bossing?"—this guide is for you. The reality is that boss progression in OSRS isn't just about combat level. It's about unlocking content , learning mechanics , building gear on a budget , and scaling difficulty at the right pace . Rush into Vorkath at combat 90 with Tier 30 gear, and you'll bleed GP on deaths. Wait too long, and you'll miss out on millions of GP/hour that could have accelerated your account. This roadmap is designed to take you from your first boss kill to endgame PvM—with exact combat level ranges, gear checkpoints, EXP/hour benchmarks, and the reasoning behind every step.

They die twice, spend 500K on gear repairs and supplies, and walk away thinking bossing isn't worth it. The problem isn't the boss. It's the progression . Bossing in OSRS is a skill, just like any other. Every boss teaches you a specific mechanic: prayer flicking, movement, eating under pressure, or managing multiple enemies. If you skip
