Berserker

Berserkers are brawlers whose bodies are conduits to the Spirit Realm. In battle they use this nexus to increase their speed, strength, and stamina. Unlike other brawlers, Berserkers fight without armor, relying on their supernatural resilience and regeneration to weather their opponents' blows. Berserkers can siphon essence from their enemies' attacks meaning they are at their most deadly when being assailed by multiple foes.
Class Skills: Rage (250) Key Attribute: Constitution
Abilities:

• Rage - When a berserker rages, all damage is partially mitigated by the character's Rage skill. The amount of mitigation is calculated by rolling rage vs. the enemy's attack roll.
• Charge - charge at a targeted enemy, slamming into it with force, staggering it and potentially knocking it prone. This can drive enemies back a number of meters that determined by the Berserker's strength. If an enemy thus driven back collides with a solid object, they take additional damage.
• Salmon Leap - leap five meters into the air
• Sweeping strikes (passive) - the berserker makes wide strikes that hit multiple enemies within range
• Feed the Fury (passive) - the berserker gets a damage bonus inversely proportional to their remaining HP.
• Unyielding (passive) - cannot be knocked back
• Savagery (passive) - HoT based on damage meted out
