NoobFury's Berserker Dark Knight

Berserker Dark Knight (Physical DK) is mostly centered around single target damage + bulkiness The DK equips are tailored to be more efficient since it can easily reach refines up to +20 ( although cards that needs refines doesn't count these "refines" so be wary on that) Still, the bonus ATK on each part + 5 allstats per piece on armor boots and muffler helps quite abit. You don't even need to card anything else.
