Great Old One

Alignment: Chaotic Evil, Chaotic Neutral, or Neutral Evil.

Devotion: A warlock with a great old one patron may add or subtract 1 from the results of d% rolls to determine their actions while confused.

Pact: The wishes and machinations of a Great Old One are unknowable. All one can do is embrace the madness and chaos. But frequently peering into the void has cost you some of your sanity. A servant of a Great Old One constantly has their mind bombarded with sanity shredding revelations. Whenever the warlock rolls initiative to enter combat, she must also roll a Will Save whose DC is equal to 10 + half the warlock’s level + the warlock’s Wisdom modifier. If the warlock fails this save, she is confused for 1d4 rounds. Because of this constant bombardment, the warlock’s mind is much more adept at handling threats. Whenever the warlock rolls a Will Save, she may roll twice and use whichever result she wishes.

Manifestations

Warlocks with a Great Old One patron gain the following manifestations at the listed levels.

Comfortable Insanity (Su): Cultist of the Great Old Ones are used to glimpses of the unthinkable and have adapted to the insanity it brings. Whenever the warlock is confused, her random actions are modified as follows:

• Act normally: No changes.
• Babble: The wearer’s babbling is chaotic and maddening. One creature of the warlock’s choice within 30 ft. must succeed on a Will save or become confused for 1d4 rounds. The DC of this Will save is equal to 10 + half the warlock’s level + the warlock’s Wisdom modifier. If the target is already confused, the duration of their confusion is instead increased by 1d4 rounds. The warlock may choose herself as the target of the babble.
• Damage self: The damage is nonlethal.
• Attack nearest creature: The warlock gains a +1 insight bonus on attack rolls against enemies and takes a –4 penalty against allies.

A confused warlock who was attacked may choose to roll a d% to determine their action instead of attacking that creature. Additionally, all warlock spells the warlock casts while confused do not expend a spell slot. As a standard action, a warlock who is not confused can choose to babble. A warlock may babble in this way a number of times per day equal to 3 + her Wisdom modifier.

Whenever an enemy targets the warlock with a mind-effecting ability, divination spell, or enchantment spell, the feedback from tapping into the warlock’s mind deals psychic damage equal to 1d6 + the warlock’s Wisdom modifier. If the ability or spell requires a Will save and the warlock fails that Will save, this damage is increased to 1d6 for every 2 warlock levels + the warlock’s Wisdom modifier. This ability also applies to enemies that attempt to observe the warlock using a divination spell such as detect evil or true seeing.
