Does Hardness and Energy resistance stack?

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?

Thank you

You would apply the save to halve the damage (if it saves), then resistance and hardness (order doesn't matter much), and then vulnerability to increase any damage that actually gets through.

You apply hardness, resistance, and vulnerability in that order. This has come up a lot at my local pfs events and we've had to look up the ruling on it. Remember though you DON'T halve the electricity damage when you use hardness for a creature.

So to use your example that 15 dmg you got would be 7 damage after every defense plays out (-5 hardness, -5 from resistance, +2 from 50% increase).

Hope that helps man and if it's the creature I think it is your players are in for a rough ride.

Remember though you DON'T halve the electricity damage when you use hardness for a creature.

Oh? And where is that spelled out in the rules?

Here.

I was asking about the Core Rules, not the Pathfinder Society's house rules.

Well the blog does refer to the Design Team making that decision, so I think it's applicable to the Core Rules as a rules clarification.

How does hardness work for creatures? Does energy damage such as cold deal half damage to creatures with hardness (Pathfinder RPG Core Rulebook 173-174) even before applying the flat numerical reduction?
When a creature with hardness sustains damage, subtract its hardness from the damage dealt. The rules for halving damage, doubling damage, dealing damage with ineffective tools, immunities, and the like only apply to damaging inanimate objects.
(This is apparently a question the Design Team has received a few times during the development of Iron Gods, so they were ready to go with an answer!)

The robot in question is not an inanimate object, and so this rule clarification doesn't apply in this situation. The robot has a reflex save, as where an inanimate object generally doesn't.

So I would think the previous Save, Hardness, Resistance, Vulnerability is the right way to go.

Justaworm didn't read. :(

...Not sure what to say to this.

Thank you all for your helpful posts.

I doubt the players will be happy with the hardness....then in addition to that the electricity resistance. I doubt they will be thrilled the electrical vulnerability applies after the first two defenses

again thank you for your help,
