(precisely it's 45%) But against certain summons with low hp (healing ward) this ability pwnz. But the mana costs are huge - you will have to pay up to half the HP of the enemy unit as mana. This ability allows you to take over your enemies summons to your side. This ability has to be researched on Tier 3 in the Arcane Sanctum, thus making it rarely used, but should your enemy use summons, it will give you a huge advantage. This alone would qualify them as perfect anti casters, but they have one more ability: Control Magic. Their third ability is their spell immunity. Additionally to that the amount of mana burned is dealt as damage to the enemy unit, which means that all units and heroes with mana die very fast when they are attacked by Spell Breakers. This ability burns 20 mana from all enemy units, and 4 mana from all enemy heroes. Their second ability is to burn mana with each attack. That means if some orc plans to build bloodlust against you, build a few Spell Breakers and the bloodlust is yours. They are Melee-units which aren't exactly THAT strong, but their abilities are where they pwn: They can steal buffs from enemy units. They are one of the best counters to casters and heroes in the game.
