Splash Trait

Source Core Rulebook pg. 544 1.1
Most bombs also have the splash trait. When you use a thrown weapon with the splash trait, you don’t add your Strength modifier to the damage roll. If an attack with a splash weapon fails, succeeds, or critically succeeds, all creatures within 5 feet of the target (including the target) take the listed splash damage. On a failure (but not a critical failure), the target of the attack still takes the splash damage. Add splash damage together with the initial damage against the target before applying the target’s resistance or weakness. You don’t multiply splash damage on a critical hit.

For example, if you threw a lesser acid flask and hit your target, that creature would take 1d6 persistent acid damage and 1 acid splash damage. All other creatures within 5 feet of it would take 1 acid splash damage. On a critical hit, the target would take 2d6 persistent acid damage, but the splash damage would still be 1. If you missed, the target would take 1 splash damage. If you critically failed, no one would take any damage.
