Hard Charger’s Melee Charge Damage Effect
Hard Charger grants a damage bonus to melee charge attacks, which are the powered up swings your character makes when holding down the attack button. Since it stacks with the other melee traits, it is worth fully leveling those before putting any points into this trait, as the others benefit you with normal strikes as well.
How to Find the Hard Charger Trait
Hard Charger is unlocked after defeating the World boss duo, Brudvaak and Vargr, found in Reisum. You can encounter them in either story or adventure mode and as they are the only world boss of Reisum, are guaranteed to spawn.
