There are so many different types of bosses in OSRS – and they are definitely not all created equally. Some require you to be focused on multiple things at once, some are very bulky, and others just deal a ton of damage on impact. This guide was created for beginners who just started bossing and are looking to work their way up as they develop their accounts. If you want a pre-developed account, you can buy OSRS accounts from Chicks Gold. This guide will hopefully give you some idea of the relative difficulty of the bosses and how to effectively handle each one. They will be split into beginner, intermediate, and pro. So let’s get into it!


Firstly, as many of you may have guessed, we have Barrows. Barrows do not require any active gear or prayer switching and do not really involve any complex strategy. There are no unique mechanics involved, as you will just be going into heads-up, 1v1 fights. All you have to do is kill each Barrows brother, get your loot potential, and raid the loot chest. Quite easy.

For the animals we have, Callisto, there are also no unique mechanics involved here except for luring them. You may take some damage during the lure, but this is not much. All you have to do is keep on dealing damage in any way you can till Callisto dies. Additionally, we have the king’s black dragon. Even though it has a more varied range of attacks, it is still very easy to defeat. All you have to do is stand in melee range with melee prayer on. You will inevitably take damage from the fire breath, but it’s very easy to kill it before you get any real damage dealt to you.


The first boss to consider here is the abyssal sire; even though this boss does require you to do some prayer and gear switches, it gives you plenty of time to do so between phases. There are three different stages to this fight. The first stage involves you taking out the respiratory systems with a ranged attack or whatever works best for you. This will then activate the second part of the fight. The abyssal sire will then come out from where it is sitting, giving you plenty of time to switch on prayers and change to your melee gear.

Once you have dealt extensive damage here, it will move down south, where it will plant itself, and then all you have to do is avoid the explosion by stepping back yourself. Avoid all the magma pools afterward, and you are good to go!

A boss who is a bit harder is Cerberus. It may not be that dangerous in itself, but certain combos can be a real danger. When ghosts and lava pools happen at the same time while you are fighting Cerberus, you might encounter some trouble as it is tricky to switch your prayers to deal with the ghosts. Once you master the prayer flicking for the ghosts, which will not take very long, and have strong gear, this is still an easy fight.


In this section, we have the corrupted gauntlet, which is significantly harder than the gauntlet because you have less time to prepare. This could put you in a compromised position based on your gear and weapons. That being said, it is a very good idea to get good at fighting gauntlets to prepare for the harder fight of the corrupted gauntlet. When fighting the corrupted gauntlet, time and resource management is direly important.

You have to be able to keep track of multiple mechanics, boss attacks, and the timing of your own attacks. The key thing to fighting the gauntlet is having perfect prayer switches, especially if you cannot obtain higher-tier gear. This is also a general rule which is good to keep in mind: good gear is invaluable.

Last words
