Abyssal

Alignment: Chaotic Evil

Devotion: A warlock with an abyssal patron may add 1/2 round to the duration of their fiendish summonings ability as well as spells of the summoning school that she casts.

Pact: The demons and qlippoth of the abyss revel in violence and destruction regardless of the victim. The frenzy of a crowded battlefield needs to become your home but it is also dangerous. Enemies flanking the warlock or creatures summoned by the warlock receive an additional +2 bonus on attack rolls and a +4 bonus on attack rolls made to confirm critical hits while flanking. Conversely, the warlock gains the same benefits while flanking an enemy. These bonuses do not extend to the creatures summoned by the warlock.

Manifestations

Warlocks with an abyssal patron gain the following manifestations at the listed levels.

Fiendish Summonings (Sp): At 1st level, The warlock may make a show of strength to beckon demons to join her in the chaotic bloodshed of battle. The warlock gains summon evil monster as a bonus feat. In addition, as a standard action, the warlock can cast summon monster I as a spell-like ability a number of times per day equal to 3 + her Strength modifier. The warlock can use this ability only to summon non lawful creatures from among those listed in the summon evil monster feat. At 3rd level, and every 2 levels thereafter, the power of this ability increases by one spell level, allowing her to summon more powerful creatures (to a maximum of summon monster IX at 17th level). These summon spells are considered to be part of her spell list for the purposes of spell trigger and spell completion items. In addition, she can expend uses of this ability to fulfill the construction requirements of any magic item she creates, so long as she can use this ability to cast the required spell.

Demon Companion: At 4th level, a warlock gains the aid of a demonic companion. The warlock can choose between babau, succubus, vrock, and quasit for their companion. This ability functions like the druid’s animal companion (which is part of the Nature Bond class feature), except that the warlock’s effective druid level is equal to her warlock level –3. The warlock may dismiss her demon companion back to the abyss as a standard action. Once per day, the warlock may summon a new demon companion by completing a ritual requiring 10 uninterrupted minutes. This ritual can replace a demon companion that has been dismissed or one that has perished under the warlock’s command. In addition, whenever the warlock would take damage that would reduce her to 0 or fewer hit points, the warlock may siphon any number of hit points from her companion. Each point is dealt to her companion instead of her. A warlock cannot siphon more hit points than her companion currently possesses. The list of demonic companions can be found here.

Down In Flames (Su): At 8th level, whenever a warlock’s demon companion or a summoned monster dies you may choose to have the creature erupt into a chaotic inferno. If so, the creature deals 1d6 fire damage to all adjacent creatures per two hit die it possessed. A successful Reflex save halves this damage. The DC of this reflex save is equal to 10 + half the warlock’s level + the warlock’s Strength modifier.

Demonic Sacrifice (Su): At 12th level, as a standard action, a warlock can command her demon companion or a summoned monster to sacrifice itself in one final attack. On the monster’s turn, as a standard action and if able, it incinerates itself and hurls itself at an enemy within reach as a melee touch attack (it may take other actions on its turn before sacrificing itself). This attack deals unholy damage equal to the monster’s hit dice (not including hit points gained from other sources). For example; a succubus making a sacrifical attack would deal 8d10 damage if it hit.

Otherworldly Roar (Ex): At 16th level, as a swift action, the warlock can let loose an abyssal roar in a show of strength empowering all monsters they’ve summoned including their demon companion. Until their next turn, empowered monsters gain a morale bonus to Strength equal to the warlock’s Strength modifier. A warlock may use this ability a number of times per day equal to their Strength modifier.

Fiendish Blessings

Warlocks with an abyssal patron may select from among the following fiendish blessings. The DC to save against these blessings is equal to 10 + 1/2 the warlock’s level + the warlock’s Strength modifier. Whenever a warlock would gain a feat, they may instead select a fiendish blessing they qualify for.

Abyssal Adaptation (Ex): Select a 1-point evolution other than pounce or reach from those available to a summoner’s eidolon. Your demon companion gains this evolution. The demon companion must conform to any limitations of the evolution. For instance, only a demon companion of an appropriate size and base form can have the mount evolution. Whenever you summon a new demon companion, you may select a new 1-point evolution for your demon companion. A warlock can take this blessing multiple times. Each time she does, she selects an additional 1-point evolution for her demon companion.

Abyssal Strength (Ex): The warlock’s Strength score permanently increases by 2 points. A warlock must be at least 18th level before selecting this blessing.

Coordination (Ex): The warlock’s demon companion gains one teamwork feat known by the warlock. If the warlock has no teamwork feats, the demon companion gains no benefit from this blessing. Each time the warlock summons a new demon companion, they may choose a new teamwork feat they possess to grant their demon companion. A warlock must be at least 6th level before selecting this blessing.

Demonic Commander (Ex): Monsters the warlock summons using the fiendish summonings ability also gain the teamwork feat granted to the warlock’s demon companion by the warlock’s coordination blessing. If the warlock does not currently have a demon companion, they may instead bestow any teamwork feat they know onto their summoned monsters. A warlock must be at least 10th level and have the coordination blessing before selecting this blessing.

Demonic Display (Ex): The warlock gains shatter defenses as a bonus feat even if she does not have the normal prerequisites. A warlock must be at least 6th level before selecting this blessing.

Each creature adjacent to the space where the monster or monsters are summoned are dealt 1d6 fire damage per two hit die the monster possesses. A successful Reflex save whose DC is equal to 10 + 1/2 the warlock’s level + the warlock’s Strength modifier halves this damage. Creatures summoned this way are dazed on their first turn.

Visage Of The Abyss (Ex): The warlock gains intimidating prowess as a bonus feat. If she already has intimidating prowess or gains it later, she instead receives skill focus (intimidate) as a bonus feat. This blessing may be selected twice.

Incarnation

Once per day as a standard action, the warlock may become an abyssal incarnation for a number of minutes equal to the warlock’s Strength modifier. Their type changes to outsider (chaotic, demon, evil, extraplanar). As an abyssal incarnation, the warlock may use their otherworldy roar ability once per round without expending a daily use. In addition, whenever the warlock uses demonic sacrifice, the warlock may command up to three monsters she’s summoned to make a sacrifical attack. The warlock may also sacrifice 1 minute of the duration of her abyssal incarnation to use her fiendish summonings ability without expending a daily use.
