Does the Explosive Bombs discovery passively increase the splash radius of ALL of an alchemist's bombs (as seems to be stated in the first line of the discovery explanation; see below...) or just the radius of Explosive Bombs, exclusively?
From paizo's site:
"Explosive bomb*: The alchemist's bombs now have a splash radius of 10 feet rather than 5 feet. Creatures that take a direct hit from an explosive bomb catch fire, taking 1d6 points of fire damage each round until the fire is extinguished. Extinguishing the flames is a full-round action that requires a Reflex save. Rolling on the ground provides the target with a +2 to the save. Dousing the target with at least 2 gallons of water automatically extinguishes the flames."
I apologize if this has been answered in other threads, however I haven't been able to find this specific issue addressed anywhere. This discovery reminds me of abilities in other games (namely MOBAs) which contains boh a passive and an active function.
Explosive Bombs exclusively. See that asterisk? It means it can't be combined with other Bomb variants with the same asterisk (like Frost and Force Bombs, or Smoke Bomb).
