Kerauno Wyrm

A hunt fish rather than a regular bite, Kerauno Wyrm appears at Zeus' Thunder of Chaos during a Kerauno Wyrm Hunt, which starts either naturally or after you catch 25 Electric Shock fish while the water is fully charged. The Exotic wyrm itself takes Starlight Worm bait, at night, in stormy weather in Spring, and the game calls it a colossal wyrm of living thunder made of blinding arcs of lightning.

The reel-in is built around dodging. Progress speed is forced to -81%, and the bar is attacked in two ways, sometimes at once: electric orbs, which swoop down 1 second after a small blue exclamation mark appears, and a lightning strike that warns for 1 second over 30% of the bar and takes more progress in the dark-yellow zone than the light-yellow one.

Landing it triggers a boss fight to break the divine seal: you must survive 45 seconds of the same attacks, which get harder at 30, 20 and 10 seconds left. Orbs deal 7-8% health and one lightning strike up to 20%, so the wiki advises holding over 50% health before the last 20 seconds. For the minigame it recommends a low-control rod such as Pinion's Aria, Fabulous Rod or Ruinous Oath.
