I'd like to talk about energy attacks and objects.
On page 173 of the core rulebook it says:
Energy Attacks: Energy attacks deal half damage to most objects. Divide the damage by 2 before applying the object’s hardness. Some energy types might be particularly effective against certain objects, subject to GM discretion. For example, fire might do full damage against parchment, cloth, and other objects that burn easily. Sonic might do full damage against glass and crystal objects.
Page 174 says:
Vulnerability to Certain Attacks: Certain attacks are especially successful against some objects. In such cases, attacks deal double their normal damage and may ignore the object’s hardness.
Page 174 also has a statement about weapons that I think can be applied here with a little stretching.
Ineffective Weapons: Certain weapons just can't effectively deal damage to certain objects. For example, a bludgeoning weapon cannot be used to damage a rope. Likewise, most melee weapons have little effect on stone walls and doors, unless they are designed for breaking up stone, such as a pick or hammer.
Page 175 then gives us table 7-13: Substance Hardness and Hit Points.
This table lists 10 different materials, some of which I think can be lumped together for purposes of this discussion (i.e. iron/steel/mithril/adamantine = metal).
We know there are 5 different energy types: Fire/Cold/Acid/Electricity/Sonic. Force I feel can be precluded for purposes of this discussion.
All rules available for reference here: PRD
My question is:
Can there be some form of consensus for PFS as to which of these rules;
Vulnerable (double damage and no hardness), Particularly Effective (full damage after hardness), Mostly Effective (1/2 damage after hardness as normal), and Immune (no damage).
Is applicable to the materials listed on the table; Glass, Paper/Cloth, Rope, Ice, Leather/Hide, Wood, Stone, and Metal.
When exposed to one of the five energy types; Fire, Cold, Acid, Electricity, and Sonic.
I personally vote that ice is immune to cold and vulnerable to fire, but I leave the rest of the choices up to all of you.
Maybe if someone could be so kind as to make some sort of table we could tally votes and come up with a final model for most general situations.
Or we could just leave it all.......subject to GM discretion.
