In melee, every time you miss because of concealment, you may reroll your miss chance percentile roll one time to see if you actually hit.
An invisible attacker gets no advantages related to hitting you in melee. That is, you don't lose your Dexterity bonus to Armor Class, and the attacker doesn't get the usual +2 bonus for being invisible. The invisible attacker's bonuses still apply for ranged attacks, however.
Additionally, you take only half the usual penalty to speed for being unable to see. Darkness and poor visibility in general reduces your speed to three-quarters normal, instead of one-half.
