Body of The Ancient Beast

Starting at 1st level, your body begins to adopt the features of your beastial patron. Depending on who or what your patron is, it's your choice what your evolution looks like. When you aren't wearing armor, your AC equals 13 + your Dexterity modifier. You also have advantage on perception checks based on sight or smell.

Breath of the Ancient Beast

Starting at 1st level, you automatically gain access to the eldritch blast cantrip and it doesn't count towards the number of your cantrips known. Whenever you cast the eldritch blast cantrip, you may instead channel the wrath of your beastial patron through a breath attack. This breath attack is a 5 foot wide line that has the same 120 foot range as the eldritch blast cantrip. All targets caught in this line attack must make a Dexterity saving throw against your spell save DC or take 1d10 force damage.
Additionally at 5th, 11th and 17th level, where you would normally gain access to multiple beams, if you use your Breath of the Ancient Beast class feature while casting the eldritch blast cantrip, you will instead increase the number of d10s rolled in one beam and widen the beam by 5 feet.
• At 1st level, 1d10 force damage, 5ft wide beam
• At 5th level, 2d10 force damage, 10ft wide beam
• At 11th level, 3d10 force damage, 15ft wide beam
• At 17th level, 4d10 force damage, 20ft wide beam.
You may use this feature a number of times equal to your Charisma modifier, afterwards you must complete a short rest before you can use it again.

Starting at 2nd level, if you use the Agonizing Blast, Repelling Blast or Eldritch Spear eldritch invocations while using your Breath of the Ancient Beast class feature, your breath attack is further enhanced.

While using Agonizing Blast, you will instead add damage equal to your Charisma modifier multiplied by each subsequent level enchantment of the eldritch blast cantrip.

(with Agonizing Blast eldritch invocation)
• At 2nd level, 1d10 (+1x Charisma modifier) force damage
• At 5th level, 2d10 (+2x Charisma modifier) force damage
• At 11th level, 3d10 (+3x Charisma modifier) force damage
• At 17th level, 4d10 (+4x Charisma modifier) force damage

While using Repelling Blast, all targets that failed the Dexterity saving throw against your spell save DC, are pushed 10ft from the center of the beam.

While using Eldritch Spear, the range of your breath attack extends to 300 feet.

Soul of the Ancient Beast

Your body continues to change into a form that can channel the power of your patron more efficiently.  Starting at 6th level, while using your Breath of the Ancient Beast class feature, targets that succeed on the Dexterity saving throw now take half damage. Additionally, after using your breath attack, you may harden your skin as a bonus action, giving you resistance to bludgeoning, piercing and slashing damage until the end of your next turn. Finally, your hit point maximum is increased by 2 and is increased by 2 again whenever you gain a level in this class.

Wrath of the Ancient Beast

Your body once again bends and morphs into a facsimile of your patron. You may choose to be a Scourge of the Seas or a Terror of the Skies.

Starting at 10th level, when not wearing armor, your AC equals 15 + your Dexterity modifier.

Once per short rest, you gain resistance to a damage type of your choice. When you take the damage type resisted by the use of this feature, you may use your reaction to immediately use Breath of the Ancient Beast, without expending one of your uses per rest, adding [roll]3d8[/roll] of the damage type reflected by this feature. You may only use this feature if you take a minimum of 20 of the triggering damage type before resistances are applied.

At 17th level, the bonus damage increases to [roll]4d8[/roll].

Scourge of the Seas

Your chosen patron is a scourge of the seas. Sailors and pirates alike had often begged their shallow gods to hide them from your master.

You now have a swim speed equal to your walk speed and can breathe underwater.

Terror of the Skies

Your chosen patron is a terror of the skies. Its legendary wingspan blots out the sun and stars.

You now have a set of wings that allow you to fly at a speed equal to your walking speed.

Hunger of the Ancient Beast

Starting at 14th level, the damage resistance that you gain from use of your Wrath of the Ancient Beast feature instead becomes an immunity. Whenever you would take damage of a type you are immune to from the use of this feature, you may instead heal for half the damage you would have taken.
When absorbing damage this way, your body feeds off it. For the next 24 hours, you feel full and satisfied, as if under the effects of a goodberry spell, and do not need to eat.
Additionally, you may forgo the feeding and/or healing to instead gain one of your warlock spellslots, if any are missing.
You may not gain a spellslot from this feature by attempting to harm yourself with the listed damage type or having an ally attack you with the listed damage type.
