Planning a boss fight
Green schools take extra damage, red ones are resisted, with the percentage beside each. The boss counters tool lists every skill, character, orb and rod for the schools a boss is weak to. Drop chances are per catch; crystals come with every catch of a boss that gives them.
Questions
How many bosses are in Heavyweight Fishing?
70 of the 133 fish are bosses: you fight them with skills before they're landed. 29 of them take extra damage from certain element schools.
Which boss gives the most crystals?
Vermilion Birdblood, 100 crystals a catch.
How do element weaknesses work?
A boss lists schools it takes extra damage from (green) and schools it shrugs off (red), each with the percentage. Skills of a weak school hit harder; bring those, and a character or orb that boosts that school.
