Benefit In melee, every time you miss because of concealment, you can 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 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 normal, instead of one-half.
Normal Regular attack roll modifiers for invisible attackers trying to hit you apply, and you lose your Dexterity bonus to AC. The speed reduction for darkness and poor visibility also applies.
Special The Blind-Fight feat is of no use against a character who is the subject of a blink spell.
A fighter may select Blind-Fight as one of his fighter bonus feats.
Benefit You gain +1 hit point per hit die. In a campaign that does not give a fixed number of hit points per hit die, this may instead bump the effective hit die. For example, a core cleric (d8 HD) would instead roll d10 for each level.
Special A character may gain this feat multiple times. Its effects stack.
Note I didn’t like the way core Toughness failed to scale with level. It’s a half-decent feat at first level when hit points are at a premium, but a few levels later is typically a wasted feat — 3 hit points don’t much matter when you’ve got 80. I changed the feat so it instead gave a bonus that scaled with level.
