Blur, Blink and Displacement, how do they stack? [Archive] - Wizards Community

While pondering a new character, when my stint as DM is finally over, I was looking at some spells that I don't normally pay a lot of attention to, for a Fighter/magic user type.

How, if at all, do the effects of these spells interact?

Does only the highest miss penalty apply?

I'm guessing they don't just add (120% miss chance, Hmmm!)

Do they they apply consecutively? ie 80% chance to hit due to Blur, if you beat that, then 50 % chance to hit due to Blink, then 50 % chance to hit due to Displacement.

ie (chance to hit = 4/5 * 1/2 * 1/2 = 1/5 = 20% or 80% miss chance).

Any thoughts would be most welcomed

Thanks

Well, blur and displacement both simply provide concealment, so they would overlap, not stack. With both, you'd just have 50% concealment.

Blink does something else, you're really not there 50% of the time. I would have you roll both effects in succession: first a 50% miss chance for concealment, then a 50% miss chance for blinking. To save time, you could just roll once for a 75% miss chance.

but doesnt blink description say miss chance is partial due to concealment and partially due to not bring there?(thus truye sight negating part of them iss chance)

so i don't think entire 50% stacks with displacement...i agree other tehnt that though

Yes, part of Blink effect is from concealment. And that's why you can make sneak-attack, while you are blinking.

Blur does not stack with displacement.
Blink only partially stacks with displacement.
Blink is 20% concealment and 20% etherealness with 10% bonus if both function.
The 20% concealment does not stack with displacement.
Therefore you should roll 50% first for displacement, and 20% second for etherealness.
Or in total:
Chance to miss = 50% (displacement) + 50%*20% (etherealness) = 60%
Thus a 60% miss chance.

Thanks for the thoughts, I'd guessed blur and displacement didn't stack (A person can hope though) and FireAge's break down of blink makes sense to me.

I would make the etherealness 30%, since you are getting more than the 20% concealment that normally gives you a bonus 10% from blink. Unless the attacker ignores the concealment, then it would be the normal 20%.

So I would require a 50% miss chance roll, followed by a 30% miss chance roll, or use the combined: 50% (displacement) + 50%*30% = 65% if you use one roll instead of two.

While we're on the topic of Blink, what happens when the Blinking individual wields a Ghost Touch weapon?

The spell description states that "Likewise, your own attacks have a 20% miss chance, since you sometimes go ethereal just as you are about to strike." But the Ghost Touch weapon description says"Essentially, a ghost touch weapon counts as either corporeal or incorporeal at any given time, whichever is more beneficial to the wielder."

If I'm reading that right, you'd never have a miss chance while Blinking if you have a Ghost Touch weapon. Is that correct?

Ethereal is different from incorporeal. Therefore Ghost Touch weapon does nothing against ethereal beings.

Hmm . . . looks like that's the case. Thanks for the tip!
