What do Lucky Strikes give?

The items are not the whole payout, and they are probably not the part you should be playing for. A Lucky Strike also raises the Prismic energy in the area around you, and it carries a chance of immediately kicking off a Prismana Flow. One good catch can change the state of the ground you are standing on, not just the contents of your bag.

That Flow trigger is a chance, not a guarantee. You cannot plan around it. What you can rely on is the item drop and the local energy bump, both of which come off ordinary catching rather than some special encounter type. Every Aniimo you go after is a roll at it.

The practical read: treat Lucky Strikes as the reason to keep catching carefully even when the Aniimo itself is nothing special. The catch you were going to make anyway is the one that seeds the area's energy and occasionally hands you a Flow on top.

Not settled: Which items a Lucky Strike drops, and whether the pool changes with the Aniimo you are catching, is not pinned down.
