Pthentraken is the pavosaurus rex matriarch, one of the three Rex Matriarchs found on Anachronia. Pthentraken uses magic based attacks and is weak to ranged attacks, specifically arrows. She counts as a dinosaur for the purpose of a Slayer assignment, although Tuska's Wrath will not deal the full damage.

Obtaining all unique drops from Pthentraken and the other two Rex Matriarchs will complete the Rex Flex feat which unlocks the title [Name] the Ferocious.

History

Pthentraken along with the other two matriarchs are experiments from the Dactyl dragonkin Kerapac, who surgically removed glands and sacs from Raksha and grafted them to the matriarchs; specifically, glands that allowed Raksha to generate electrical charges for offense and camouflage were grafted onto Pthentraken. Kerapac considered the surgery a success, despite the lowered potency of the ability the matriarch displayed compared to how Raksha was able to use it.

At some point, Kerapac used either the eggs of the matriarchs or the offspring of their eggs in experiments to combine the traits of the other matriarchs along with dragonkin blood. These experiments eventually led to the creation of the egg that would hatch into the Queen Black Dragon, with another dragonkin Phalaks attempting something similar; his experiment led to the creation of the King Black Dragon. Kerapac's experiment kept many of the qualities related to size and power of the dinosaurs, while Phalak's experiment kept the original attributes obtained from splicing Raksha's glands.

Update history

This information has been compiled as part of the update history project. Some updates may not be included - see here for how to help out!

• patch 26 April 2021 (Update):
  • Affinity has been adjusted, increasing the Matriarchs' base chance to be struck in combat
  • Projectile speeds have been adjusted so damage should better line up with the projectile hitting the player
  • Slayer XP has been increased
  • Combat XP has been reduced
  • Shards can now be correctly combined into Hearts
  • Rare drops from Rex Matriarchs will now consistently trigger a broadcast

• hotfix 26 April 2021 (Update):
  • The arena entrance has been adjusted to prevent it being used as a safe spot
    • This also resolves instances of low XP and/or no drops

• update March 2021 (Update):
  • Added to game.
    • This week the Rex Matriarchs come roaring into the game with a new combat challenge for experienced fighters.
    • You'll go up against three respawning bosses. Each has a different strength to test your mettle, but also a different weakness to be exploited. Grind those kills and earn powerful rewards to boost your Combat playstyle, or maybe even get your hands on the iconic Laniakea's Spear - T90 damage / T75 accuracy is not to be sniffed at, plus, it'll give you 5% extra poison damage and +5% chance to apply poison when used. Veteran RuneScapers may recall classics such as Dagannoth Kings while new challengers will enjoy a brutal test of their combat mastery. Note that access to Anachronia is required to take on this challenge. So what are you waiting for? Grab your best gear and head to central Anachronia. The lair of the Rex Matriarchs awaits...
