The Real Meaning of "Concealment"

[Fatespinner]

So, spells like blur and displacement give a benefit to their targets that results in a miss chance. Blur specifically states that it grants concealment (and the commensurate 20% miss chance). Displacement on the other hand, states that the target benefits from a 50% miss chance "as if it had total concealment."

Since displacement states that "unlike actual total concealment, displacement does not prevent enemies from targeting the subject normally," I am inclined to believe that true strike basically allows the caster to ignore the effects of both blur and displacement, albeit for only a single attack roll, because the text for true strike states that "you are not affected by the miss chance that applies to attackers trying to strike a concealed target." Does this seem accurate? Or should it be because displacement is not "actual" concealment, the effects of true strike (at least the negating of miss chance) are nullified?

This should be a fun thread.

I feel that since true strike states 'miss chance' and 'concealed' in its wording, it should negate both spells. Because you are not affected by miss chances, and you can strike concealed targets. The target does not have to be both concealed and have a miss chance for the spell to work. The spell negates both conditions.

[Laughing Goblin]

I agree, I think True Strike would negate any miss chance you would have for attacking a target with either Blur or Displacement cast on them.

It would not, however, negate the miss chance of someone with say Blink, which has a miss chance that does not stem from concealment.

Blink is a little tricky. I'd say that the regular 50% is unaffected since true strike can't make you hit what isn't there to be hit. However, the 20% for someone able to strike ethereal would be negated. The 20% for being able to see invisible would not be negated.
