Any Dual/Long Sword that could help me with fighting Stygian Zinogre?
Stygian Zinogre is weak to Thunder then Water. He is also very weak to Slime. I suggest making Longswords/Dual Swords that have Thunder, Water or Slime attributes. Attack armor skills (like Sharpness +1, Challenger+1/2, Attack Up, etc.) also help in making your quests end faster.
