Can poisons be used on splash weapons? (And on alchemist bombs?)
"One dose of poison smeared on a weapon or some other object affects just a single target. A poisoned weapon or object retains its poison until the weapon scores a hit or the object is touched (unless the poison is wiped off before a target comes in contact with it).
Applying poison to a weapon or single piece of ammunition is a standard action. "
Seems like it might work but only apply to the target, not delivering poison with the splash?
Also, from that reading, could you apply poison to a ray attack from a spell you had cast?
