Osgrun the Defiler Champion Lore Synopsis
The story begins with a Dwarf grieving the loss of loved ones taken too soon, deaths that he refuses to accept as final. He resents his people for surrendering to fate, believing that true warriors should never yield. His anger grows into a conviction that death itself can be defeated, and he becomes determined to find a way to restore those who were lost. Unlike his kin, who accept mortality without resistance, he believes that through knowledge and persistence he can reclaim what has been stolen from him.
His quest leads him down a forbidden path. He experiments with runes, rituals, and dangerous magic, borrowing from tombs and secret places, determined to perfect a method of resurrection. The other Dwarves see his work as blasphemy and cast him out of Gloomdeep Hold. Yet banishment gives him a strange sense of freedom, allowing him to pursue his studies without restraint. Though branded a heretic, he sees himself as a saviour, striving to replace sorrow with joy by returning the dead in their true forms rather than as twisted corpses.
As he advances in his craft, he learns to harness life-force itself, using it to heal wounds, strengthen his body, and bend the will of the weak-minded. He creates enchanted jetstones to store and release this power, proof of his growing mastery. Along the way he realises that his ancestors were mistaken to reject the gods entirely. In secret he listens to the dark whispers of Siroth, who offers guidance through fragments of truth, never revealing everything at once but always nudging him toward greater discoveries.
One such revelation is a name: Gronjarr. The Dwarf embarks on an exhaustive search through the cursed libraries of Ireth, enduring torment from forbidden texts, hostile spirits, and other guardians of knowledge. His sacrifices are great, yet his perseverance yields the story of Gronjarr, a figure present at the Fall of the Dwarves who vanished while storming the runescript archives of Gloomdeep Hold. These archives, sealed and forgotten for centuries, may contain the very secrets needed to fulfil his ambition.
The outcast resolves to return home and uncover what lies within the archives. With the knowledge hidden there, he believes he will not only surpass his current power but also come closer than ever to restoring the ones he loved. His journey is no longer just about revenge against his people’s blindness but about seizing the chance to triumph over death itself. What began as grief has become an unrelenting pursuit of forbidden truth, one that promises both salvation and ruin.

Skratch: GAME CHANGER!! Osgrun The Defiler Showcase | Raid: Shadow Legends
This guy is a walking hate crime in arena. I have him paired with Padraig who is three star awakened intimidating presence with 200 speed and this moved me from silver to gold 3. He great in any area of the game where turn meters can be decreased. He’s a monster when he comes to eternal dragon as his a1 permanently locks her abilities. Good for fire knight. Great for potion keeps. Plus when paired with another ally attacker, like padraig, he doesn’t need to be the fastest as his a1 makes up for any difference. Run with high accuracy and speed for best results.
