Boss categories - what sorts of RS gold supervisors are there. All of the bosses could be divided into smaller classes depending on their goal. Primarily, there are PvM bosses that are unique monsters scattered around Gielinor. They come in various forms and they really much differ in strength - from fairly simple to quite demanding, although, for late game players they should not be a big threat.
Raid bosses are distinct story, though. They pose a much larger threat as they're designed to fight many gamers in the same time. Presently there are only two of them - Excellent Olm and Verzik Vitur that you can fight in the conclusion of Chambers of Xeric and Theatre of Blood raid respectively.
If you have ever wandered around Wilderness then you probably met one of those Wilderness bosses. Those enemies have been scattered from the Wilderness area waiting for unexpecting adventurers to attack them. All those have a opportunity to shed a Dragon Pickaxe therefore it may be a good idea to resist against one should you ever meet him. Although, they're not simple it's worth noting that many of these are not extremely dangerous to seasoned players.
Next category belongs to Sporadic Bosses which as the name suggest don't always reside in 1 place waiting for gamers who would like to challenge them. Rather, Sporadic Bosses demand a special item which may be acquired by various activities so as to muster them. They come in various strengths so it's hard to quantify their difficulties.
Skilling Bosses are much different than the prior ones. They're fought not to the loot rather than for the fighting encounter but rather for experience in different areas. Skills such as Firemaking, Woodcutting, Herblore, Fletching, and Farming may be employed to battle against Wintertodt which is the boss in the minigame of the same name.
Slayer Bosses are most likely the most common on this list. They come because the larger and stronger versions of cheap RuneScape gold monsters that are assigned by slayer masters. If participant unlocks"Like a Boss" skill in his Slayer Master then he can start hunting for these special creatures. They frequently drop very precious things but they also have fairly high requirements so as to be struggled with. Aside from Slayer skill mentioned before adventurers have to get high enough Slayer skill level and very high stats for such a fight.
