Practice trick shots on weak, disposable fish before trying them on a boss

A flashy finishing shot (like a 360 no-scope) increases the sale value of the kill, not just the achievement progress. Weaken a normal fish first to create a safe opening, then practice the trick shot on the kill. Don't try to learn the timing during a boss fight, where one missed attempt costs you an opening.

Landing trick shots (like a 360 spin kill with no scope) earns bonus in-game currency, shown as a stacking string of named multipliers.
