Concealment Bonuses

[poundpuppy30]

I've a question about concealment. Can a person have over a 50% chance to miss them from concealment? Reason I'm asking is what if you had several types of concealment benifiets on at the same time. What if a person had cloak of displacement; which makes them look like they are 2 ft from where they really are and gives them a 50% chance to miss them. Now that same person casts blur on themselves which makes them blurry and while blurry they are 20% chance to miss. Don't forget they are still wearing the cloak so they are now blurry and look to be 2 ft from where they really are. Now lets throw in the feat called lightning stance which lets this same person have a 50% miss chance for 1 round if they take two actions to move in the same turn by withdrawing. So now you have a displaced, blurry person using lightning stance to withdraw. Would they only get a 50% chance to miss them or would they get 120%. In theory each one of these things would hinder your attacker from hitting you by themselves but the question is do any of them stack so it makes it harder to hit you? Please don't even ask if they overlap I've already got an overlap question going on about something else in another thread....lol

Yes they can but no, they do not stack. I think there are some corner cases that can give you a 100% concealment, but that is not from gaining 50% concealment twice. It is more so from spells that are opaque or something like that, I can't remember.

For the most part, 50% is the highest playable. That is what invisible creatures get.

You take the highest number from all sources, just as you do for cover.

Wierd you would think the displacement, blurr, lightning stance would combine since each makes the person harder to hit but oh well.

I see on pg 197 of the core book where it says "Multiple concealment conditions do not stack." It just seems wierd that they dont.

[Claxon]

Well the cloak of displacement is made using the blur spell. So it's the same effect twice.

Further rules say that multiple concealment status do not stack, mostly as a balance issue so you can't do the exact thing you're talking about because everyone would walk around 70% concealment or more.

[poundpuppy30]

I think you mean the cloak of displacement is made from the spell Displacement since Displacement gives 50% concealment and Blurr only gives 20% concealment.

[poundpuppy30]

In theory it should be allowed since each one adds to it in a different way. It's kind of how you wear armor, have dex bonus, can strap on a shield for more armor and can still add natural armor for even more armor class and yet can add feats for even more ac boost.

[Komoda]

If you wear full plate and add leather, your AC does not go up. Concealment works the same way.

[poundpuppy30]

No but if you have leather on and put plate over it the leather helps against your bare skin against the plate plus thats a thinker thickness something has to penetrate to injure you in "theory" that is. Remember what works in science in the real world as thicker armor doesn't work the same in pfs.

If you did want to stack concealment as a house rule you can either:

Roll each miss chance in succession and if any indicates a miss the attack misses.

Roll a single miss chance, but to do this make sure you don't just say 20% and 50% totals 70%, rather to hit you need to roll 80% and 50% so the chance to not miss is 40% (80% x 50%) and so the combined missed chance is 60%.

50% and 50% and 20% would be a combined miss chance of 80% (as to not miss you need 50% x 50% x 80% = 20%).

I'm sorry DigitalMage..

umm..what?

I don't think I'm smart enough to follow that, LOL.
