Taking the best from 2 "armors" ?

I ran into an issue with a character I got in mind earlier, when I came to realize that the armor bonuses I had planned for wouldn't stack.
So I was wondering would you be able to combine the 2?

1 Is a physical armor while the other is a tempoary armor gained through ability/effect/spell.

Let's assume the physical armor gave a +6 Armor save and fire resistance x, while the tempoary armor grant +8 armor and DR/x

Would I then be at + 8 armor, + x fire resistance and DR/x as long as the duration hold?

No. Whatever gives the highest AC bonuses totally suppresses the properties of the other. your temporary armor would make the physical armor essentially "not there", you'd have the DR but not the fire resistance.

This was to prevent cheese items such as +1 Bracers of heavy Fortification being worn with +5 Platemail of Wonderfulness.

Can I ask what ability/effect/skill your using? That could make a difference.

Not likely. Armor bonuses don't stack, period. Thems the rules. If someone casts Mage Armor which grants a +4 AC bonus on someone who's wearing +1 leather armor of fire resistance and light fortification, all of the properties of the leather armor are suppressed.

If the abilities are from actual armor abilities like those found in the magic item chapter, the one with the higher enhancement bonus surpresses the other item, just like LazarX said.

However, if the abilities are from spells or similar, they might stack. For example, using a +1 padded armor of fire resistance while at the same time being under the effect of a Mage Armor spell will yield you a +4 AC and fire resistance. If that mage armor spell was instead bracers of armor, you'd have just +4 AC and no fire resistance because the bracers surpress the padded armor.

The rules on armor stacking make no distinction between actual armor and spell effects granting an armor bonus.

Well the armor bonuses in question would be one Granted by the "heavens Mystery" called "Coat of Many Stars" that start out giving +4 armor bonus and eventually +10 armor bonus and DC5/slashing.

The Armor in Question is pretty much any armor that could function as best as possible with this.

I really like this mystery option, and It's kinda sad to ditch it due to making magical armor completely useless :/

No. Whatever gives the highest AC bonuses totally suppresses the properties of the other. your temporary armor would make the physical armor essentially "not there", you'd have the DR but not the fire resistance.

Unless I am missing something, that is only true for Bracers of Armor, as that is the only place the rule appears. That rule is never mentioned in the section dealing with magic armor. Its not a general rule of how magic item interact, its a specific rule about how Bracers of Armor interact with magical armor.

So while the armor bonuses would not stack (and you would take the highest one), you should still get all the bonuses from both your armor worn and the other effect. As long as you aren't trying to combine magical armor with bracers of armor.

I can think of one exception to this rule, from the PCCS and AdvArm... the Armored Kilt specifically states it can be worn as light armor, or added to other light or medium armor.

The rules on armor stacking make no distinction between actual armor and spell effects granting an armor bonus.

Do you have a reference to that, other than the specific bracers of armor?
