Kroz Wallbreaker | Raid Shadow Legends

Kroz Wallbreaker Overview

They say the ground trembled before the fortress fell. Kroz Wallbreaker, the Spirit affinity Legendary champion of the Ogryn Tribes, is not just a warrior, he is a calamity given form. His armor glows with molten fury, cracked like scorched earth and bound with chains that once restrained him. Massive spiked gauntlets serve as his weapons, forged to mimic the battering rams he once embodied. Raised by Dark Elves as a war-slave and stripped of his identity, Kroz became a living siege engine, feared across Teleria for the explosive payloads he hurls and the devastation he leaves behind. His lore speaks of a creature so powerful that arrows bounced off him and spells dissolved on impact, a beast whose fists and bombs tore through garrisons and collapsed entire battlefields.

Kroz’s combat style revolves around explosive control and battlefield manipulation. His skill Battlefield Sapper (A2) places Bomb debuffs on all enemies without triggering an attack, allowing him to bypass affinity penalties and land his setup reliably. For each enemy affected, he gains Turn Meter, accelerating toward Mangonel Maul (A3), which reduces Bomb countdowns and places Block Active Skills. This sequence primes his bombs to detonate just as enemies prepare to act, catching them in a trap of their own timing. Bombs placed by Kroz ignore 100% of defense and deal quadruple damage to champions protected by Stoneskin, making him one of the most effective counters to that set.

What makes Kroz especially versatile is his synergy with other Bomb champions. He benefits from Turn Meter boosts even when allies place Bombs, and his countdown-reducing abilities affect all Bombs on the field. This means he can follow up on setups from other champions or lead the charge himself. His skill Pulverizing Pummel (A1) adds further utility by reducing Bomb timers and potentially stunning targets, giving him both offensive and control capabilities. The ability to place Block Active Skills also makes him a strong pick against Mythical champions, preventing them from triggering their powerful Metamorphosis effects.

His passive, Bomb Breacher, reinforces his role as a tempo driver. Every Bomb detonation fills allies’ Turn Meters, and when a Bomb kills, Kroz has a chance to take an Instant Turn. This mechanic rewards aggressive play and punishes teams that fail to cleanse or mitigate his setup. In wave-based PvE content like Faction Wars, this translates into relentless momentum, allowing Kroz to chain his abilities and keep enemies from recovering. However, like many Bomb champions, his performance dips in longer fights where sustained damage is required. His strength lies in overwhelming force and rapid execution, not drawn-out battles.

Though the Arbiter now holds his leash, Kroz Wallbreaker remains a tragic figure, unredeemable, unstoppable, and unleashed only when the stakes are dire. His mind may be lost, but his purpose is clear: to break walls, crush formations, and leave nothing standing. In Raid Shadow Legends, he is not just a champion. He is the tremor before the collapse. Players now have the chance to summon Kroz Wallbreaker through an ongoing Fragment Fusion event, running from November 20 to December 3 2025. By participating in special events and tournaments during this period, they can collect the necessary fragments to fuse him into their roster.

Kroz Wallbreaker Champion Lore Synopsis

The tale begins with the fearful account of Stregolei, an Aravian guard-captain, who describes a monstrous Ogryn that struck with the force of an earthquake. This towering brute wielded fists like battering rams and hurled strange devices that erupted in smoke, fire, and choking fumes. Arrows and spells proved useless against its immense bulk, leaving defenders with no choice but to abandon their garrison before being crushed beneath collapsing stone. The creature was none other than Kroz, later infamous as the Wallbreaker, whose destructive power became the stuff of legend.

Kroz’s origins were grim. Stolen as a child, he was raised by the Dark Elves to serve as a war-slave. His spirit was broken through endless torment, leaving his body scarred and his mind shattered. Reduced to little more than a beast of burden, he was stripped of individuality and trained to obey like a war hound. The Dark Elves exploited his unnatural resilience, encasing him in colossal armour and equipping him with spiked gauntlets. They burdened him with volatile bombs crafted from the secretions of giant beetles, turning him into a living siege engine designed to obliterate fortifications and scatter armies.

His relentless destruction earned him the dreaded title of Wallbreaker. Kroz smashed through barricades, flung warriors aside, and tore apart formations with ease. Yet his mindless rampages eventually led to his capture, and he was drawn into the Arbiter’s cause. During one assault on an Aravian stronghold, his bombardments and crushing blows triggered a catastrophic collapse. The battlefield split open, swallowing soldiers and stone alike into a vast abyss. Amid the carnage, Kroz found himself face to face with a High Elf mage who wielded a powerful Shard.

The mage was no ordinary opponent but a Vault Keeper, guardian of one of the Arbiter’s hidden Vaults. The Aravians had deliberately built their fortress above this site, intending to lure Kroz into a trap. Recognising that brute force could not defeat him, they sought instead to imprison him within the Shard. As the Keeper invoked ancient magic, the Shard’s consuming power engulfed the Ogryn, binding the menace of Durham Forest and ending his reign of devastation.

Though contained, Kroz’s fate remained tragic. The Arbiter herself attempted to restore what had been stolen from him, but the torment inflicted by the Dark Elves had left his mind beyond repair. He was destined to remain a weapon, summoned only in the gravest of battles. To spare him further suffering, the Arbiter keeps him in the Shard’s timeless slumber, granting him the only mercy possible: peace within eternal sleep.
