Also it should be stated that all fish punish the player for reeling during high stamina. 50% stamina = 50% line damage taken. Also, if a fish is using an active skill (Angerjack's Gigant Charge), using Pull will deal a massive amount of damage to line HP (20% in Angerjack's case.) You can tell when he's still doing it by the glowing aura and the angry mugshot. It's really hard to convey how mechanics works sometimes and between Fishing Tips and the Fishing Manual, I don't know if I succeeded.
