Q14
Can an Alchemist qualify for Arcane Strike despite the fact that they don't actually cast spells? Is there an answer or it's just a DM call?

Q15
The Rogue ability Trapfinding specifically mentions that it allows the Rogue to use Disable Device to disarm magical traps. Are there other ways to disarm such traps other than Dispel?

Q15a
Can a caster or half-caster class use Disable Device (supposing that they either get it as a class skill or grab it as such via traits) to disarm such traps? Seems weird that a non-casting class knows how to disarm magical traps but a class with actual knowledge of magic doesn't.

Q16
Per RAW PF rules, are the lists for Summon Monster/Nature Ally, Familiar, Improved Familiar, etc set in stone or they're just guidelines to what you can do with these spells/feats/whatever they are?
