Glimpses of Hyboria
You know how to ﬁght when you are unable to see.
Beneﬁt: In melee, if you miss because of concealment, you can reroll your miss chance once to see if you actually hit. An invisible attacker gets no advantages related to hitting you in melee. That is, you can still dodge or parry your assailant and he does not get the usual +2 bonus to melee attack rolls for being invisible. The invisible attacker’s bonuses do still apply for ranged attacks, however. 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 of normal, instead of one-half.
Normal: Regular attack roll modiﬁers for invisible attackers trying to hit you apply and you cannot dodge or parry your attacker. The speed reduction for darkness and poor visibility also applies.
