Can an alchemist take two archetypes that both reduce the die size of their bombs? For example, in Ultimate Magic, both the Clone Master archetype and the Reanimator archetype reduce bomb damage by one die size. Otherwise, they don't interfere with each other. Can an alchemist take both, and have the standard bombs do Nd3 damage?
(This may also apply to other alchemist archetypes that I don't know about, or haven't been published yet.)
No, they both modify the same class ability.
If it's not PFS, you can ask your GM for an exception, of course.
