Alchemical Bombs

Source GM Core pg. 244 2.0
An alchemical bomb combines volatile components that explode when the bomb hits a creature or object. Most alchemical bombs deal damage, though some produce other effects. Bombs have the bomb trait.

Bombs are martial thrown weapons with a range increment of 20 feet. When you throw a bomb, you make a weapon attack roll against the target's AC, as you would for any other weapon. It takes one hand to draw, prepare, and throw a bomb. The bomb is activated when thrown as a Strike—you don't have to activate it separately. As consumables, bombs can't have runes etched onto them, have talismans attached to them, or benefit from runes granted in other ways (such as from spells or from items that replicate runes from other items). Spells and magic items that give you a bonus to all your attacks (or to all thrown weapons, for example) can still apply to them.

Splash Trait

Source GM Core pg. 244 2.0
Some weapons and effects, such as alchemical bombs, have the splash trait. When you use a weapon or effect with the splash trait, you don’t add your Strength modifier to the damage roll. A splash weapon or effect deals any listed splash damage to the target on a failure, success, or critical success, and to all other creatures within 5 feet of the target on a success or critical success. On a critical failure, the weapon or effect misses entirely, dealing no 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 throw a lesser acid flask and hit your target, that creature takes 1 acid damage, 1d6 persistent acid damage, and 1 acid splash damage. All other creatures within 5 feet of it take 1 acid splash damage. On a critical hit, the target takes 2 acid damage and 2d6 persistent acid damage, but the splash damage is still 1. If you miss, the target takes only 1 acid splash damage. If you critically fail, no one takes any damage.
