RS3 bestiary for Ironmen
Look up any monster: its combat level, what it's weak to, the Slayer level it needs and everything it drops. Each page also works out which items that monster is the best, easiest or only source of, so you know what a trip is worth before you go. Item drops link to how to get anything, and bosses to the Ironman boss order.

Common questions about RS3 monsters
How many monsters are in the bestiary?
1,651 monsters with a drop table or a Slayer requirement, each with its level, life points, weakness and full drops. Data last fetched on 2026-10-09.
What does “only source” mean on a monster page?
No other monster in our data drops that item, so that monster is the only way to get it as a drop. “Best rate” means the most expected drops per kill of every monster that drops it.
Which monsters need a Slayer level?
188 of them. The highest requirement is 117 Slayer, for Imperial mage akh, Imperial ranger akh and Imperial warrior akh. Without the level you cannot damage them.
How do I find what a monster is weak to?
Each monster page lists its weakness, which can be a combat style, a spell element or a weapon type. The weakness filter above narrows the bestiary to monsters weak to one of them.
