In addition to blessings offered by their patron, all warlocks have access to the general fiendish blessings.
Commune (Sp): You can cast commune once per day as a spell-like ability. Casting commune in this way still requires 10 minutes. You can only use this to contact your patron. At 14th level the time required to cast commune in this way is reduced to 1 minute. A warlock must be at least 10th level before selecting this blessing.
Damned (Ex): The warlock gains a damnation feat as a bonus feat. At 12th level, the warlock is treated as if they had an additional damnation feat for the purposes of determining the benefit of all damnation feats.
Devil’s Deception (Ex): A warlock with this blessing gains skill focus as a bonus feat. They must choose bluff or disguise. At 8th level, once per day a warlock with this blessing may cast nondetection on themselves as a spell-like ability.
Embrace The Shadows (Su): As a standard action 3 times per day, the warlock can enhance her sight, granting darkvision out to a range on 60 feet. The enhanced senses last for 1 hour.
Empowered Charisma (Ex): The warlock’s Charisma score permanently increases by 2 points. A warlock must be at least 20th level before selecting this blessing.
Eternal Youth (Su): A warlock with this blessing has been granted a release from time’s arrow. From this point forward she takes no penalty to her physical ability scores from advanced age. If the warlock is already taking such penalties, they are removed at this time. A warlock must be at least 20th level before selecting this blessing.
Fel Flight (Ex): The warlock gains leathery or scaley wings allowing them to fly as the spell fly for a number of minutes per day equal to their warlock level. These minutes do not need to be consecutive, but they must be spent in 1-minute increments. They may select this blessing multiple times; each time they do so, they add their warlock level to the number of minutes per day that they can fly with the wings. Flying with wings is part of normal movement and does not require any action to activate. A warlock must be at least 6th level and have the fel hide blessing before selecting this blessing.
Fel Hide (Ex): The warlock’s skin has grown thick and leathery or scaly to match their patron. They gain a +1 natural armor bonus to AC. At 6th level, and every four levels thereafter, this bonus increased by 1 (to a maximum of +5 at 18th level).
Fiendish Obedience (Ex): The warlock gains fiendish obedience as a bonus feat. They must still meet the prerequisites.
Hellish Resistance (Ex): The warlock has been tempered in the fires of hell and gains resist fire 5. This resistance increases to 10 at 10th level, and 15 at 15th level. At 20th level, they gain immunity to fire.
