Soulbound Summoner

A soulbound summoner’s metaphysical connection with his eidolon has profound effects on both of them. The eidolon’s alignment always matches that of the soulbound summoner, regardless of its subtype. In addition, at 1st level, the summoner must choose an oracle curse, using his summoner level as his oracle level for determining the curse’s effects. Once this choice is made, it cannot be changed. A summoner that gains spells for his list of spells known as a result of his curse must be able to cast spells of the appropriate level in order to cast the learned spell. The glowing rune that the soulbound summoner shares with his eidolon always appears on a place symbolic of his pactbond curse. For example, a summoner who chooses the clouded vision curse might have his summoner’s rune manifest on one of his eyes, while a summoner who chooses the tongues curse might have his summoner’s rune appear on his lips. A soulbound summoner’s eidolon is summoned from his own psyche rather than a different plane, so spells such as banishment and dismissal do not work when cast on the eidolon. This alters the eidolon class feature.

The essence of a soulbound summoner’s eidolon resides within the summoner’s mind and soul instead of a home plane, and he can use this connection to restore his eidolon with his own vitality. The summoner can use his life link ability to sacrifice any number of his hit points without using an action. Each hit point sacrificed in this way heals the eidolon for 1 point of damage. The soulbound summoner can use this ability even after the eidolon has been killed and sent back to its summoner’s mind; if the eidolon is healed enough that its hit point total is above 0, it can be summoned again as normal. This alters life link.

A soulbound summoner’s eidolon is usually the result of unintended magic, trauma, or a singular pact, instead of rigorous arcane study. Soulbound summoners do not gain the ability to cast the summon monster or gate spells as a spell-like ability.

A soulbound summoner’s eidolon gains power from its unusually strong bond with its summoner. At 3rd level, and again at 5th, 7th, and 9th level, the eidolon adds 1 point to its evolution pool. At 11th level, and again at 15th, 17th, and 19th level, the eidolon adds 2 points to its evolution pool. At 7th level, the eidolon can select evolutions even if it does not meet the subtype requirements for that evolution. At 13th level, the eidolon can draw from its summoner’s power to cast spells. The spell must be a spell that the summoner knows, and the summoner must expend two spell slots of the same spell level or higher to allow the eidolon to cast the spell. Expending spell slots in this way does not take an action. The eidolon uses the summoner’s caster level, feats, and casting statistics for all spellcasting purposes. The eidolon must be able to meet all other requirements for casting the spell, such as being able to speak for spells requiring verbal components and providing any material components or focuses for spells that require them. The eidolon must be able to move its body to cast spells with somatic components, but it does not need to have the limbs (arms) evolution.
