this Berserker is a JOKE. wanna make him EPIC and MANLY? than throw this shitty sword away and give him...AXE ! and than make him 2x better and give him SECOND AXE. than give him more stronger skills, set his mana to zero- he is cocky berserk, aka Rambo, not some tiny elven bard. His skills may use : nothing/rage/blood of his enemys. And character like that could be named Berserker!! so far he has bigger sword than warrior,(that is better. WHY? no unlocking, tiny sword---> better class. that makes sense!)and shitty skills (there are 2-3 good one, hell yeah, sucha big choice)
There will be a way to earn some Gold in-game soon, for free. So you'll be able to use that to reset your skills. :)
