I have been looking through a PFS scenario I am planning to run. I have noticed that one of the "monsters: in the scenario is a robot.
This robot has hardness 5, electricity resistance 5 and its vulnerable to electricity. Its reflex save is +5.
What happens if this creature is subject to a lightning bolt spell, save DC 18, 5d6 damage?
I realize first the robot would make a reflex save =1d20+5 vs DC 18 to halve the damage
Assuming it fails its reflex save and is subject to 5d6 points of electrical damage, lets say 15
points, How does the hardness, the resistance, and the vulnerability come in? Which to you apply
first second and last? Oh and does hardness and resistance stack?
