Fish boy gets a bad rap. As an AoE piercer he is not in high demand and he is strictly outclassed by Nyx in most content and in some cases even Maul. However, his AoE single burst hitting 1000% damage is nothing to scoff at and makes him viable in late-game GR2 and GR3. With solid Awakenings, a good EXP farming passive, and partner bond with Reve, Razaak is a totally acceptable hero but not much more.
