New Boss - Rex Matriarch: Osseous

Written by developer on . Posted in RuneScape News

New Boss : Osseous

  • Help out in the pursuit of Archaeological enlightenment and learn a little more about Anachronia
  • Take on this new mid level boss encounter featuring the Skeletal Matriarch Osseous!
  • Get your hands on a new Necromancy combat ring that synergizes with your necrosis abilities.

Welcome to Jurassic Park

The Rex Matriarchs were a triple threat of dangerous dinosaur dames that challenged you to branch out of 1 combat style and use another, now you will need to flex those Necromancy skill's as some bumbling archaeologists have unearthed the best kept secret on Anachronia.

Osseous, The tyrannical terror, the skeletal sovereign, the most dangerous pile of bones this side of Catherby... you get the picture. Complete a short quest and trek through the Rex Matriarchs lair into the bone laden ossuary where you may have unwittingly (or wittingly) helped bring forth the fourth Rex Matriarch!

Bones? Smones. I am a master necromancer

Your mastery over the undead will definitely be needed to combat Osseous as like the previous Matriarchs she is highly resistant to all damage except Necromantic so better bring along the undead gang to help face this foe, Or even bring some friends! This is not a solo encounter!

Osseous will challenge you with a variety of attacks , from throwing ranged projectiles or using spirit energy to smashing you with its tail and summoning minions to chomp on your ankles. You will need to use your abilities and movement to control the battlefield and strike down your foe.

To the seasoned boss hunter, Osseous will pose more of a challenge then the other Matriarchs but is more approachable than the biggest late game bosses. This boss is hoping to teach more mechanical combat skills around dealing with priority enemies, using your damage at the correct times, evading dangerous attacks etc.

Rewards

Osseous will be following in the footsteps of the previous matriarchs but will come with her own unique collection log separate from the others.

This log will include a brand new Necromancy combat ring that will enhance your ability to gain Necrosis stacks

A new Boss pet

A new title for completing the log called "the Skeletal"

And you will be able to find Jail Cell Keys which can be used to free up to 3 different baby dino pets!

Free my boi he ain't done nothing wrong.

Alongside these new rewards there will be some crossover with the over Matriarchs loot tables as the standard drops from the original 3 will also drop from Osseous too with some tweaks.

History of the update

The three original Rex Matriarch's were released back in 2021, The intention was to make a trio of bosses that were a more challenging version of the Dagannoth Kings. The idea of adding a fourth matriarch is not a new one. For those players with a keen eye, you may have noticed this with a few hints scattered around the lair.

With the idea planted, Osseous' design was excavated in Game Jam by mods Abe, Camel, Shrike and Rain (with plenty of help from other Mods), where they built upon the skeleton of the original idea. Gamejams have always been a great opportunity to try out some design ideas and Osseous gave us the opportunity to flesh out a pre-existing area and make something that's fun, a bit more hands-on difficulty wise, and also rewarding for players.

With this project leaping from GameJam to a more active production we wanted to respect the original Rex Matriarchs design while continuing to incorporate Necromancy elements deeper into the world and we hope that this blending of the two resonates with the players!
