I came across an old character of mine that has a summoner class option called Persistent Eidelon. It replaces a summoner's Summon Monster SLAs with the ability for the Eidelon to remain while the summoner is asleep unconscious or even dead. I know that this isn't Home brew and I doubt its third party material but I cant seem to find where this Class feature came from. I copy and pasted it into my Character sheet from where i got it originally. I'm trying to find the origin of the class feature if possible. Copied text to follow:
Persistent Eidelon
This archetype applies to the summoner, but affects the eidelon. A persistent eidelon does not become banished if it's summoner is unconscious, asleep, or otherwise incapacitated. Even death does not banish the eidelon.
Benefit: The eidelon, once summoned, is not banished by the summoner being asleep, unconscious, or even dead. However, if an eidelon is reduced to 0 hp or banished while it's summoner is in one of these three states, then the eidelon is banished and cannot return until it is resummoned by the summoner. The eidelon cannot be healed by any means while his summoner is unconscious, asleep or dead, not even by friendly clerics or other summoners. The eidelon must still stay within it's proscribed distances of the summoner to remain on the physical plane. If they move far enough away from the summoner's body to lose hp, they are banished instead.
If the summoner dies, the eidelon is living on borrowed time. It cannot leave the body of it's summoner (although it may pick it up and take it with it, if it has sufficient strength and size). The eidelon cannot heal while it's summoner is dead, either. Thus the eidelon's only choice is to take it's summoner to a friendly party willing to resurrect or reincarnate them, or to bury the summoner in a safe place and then return to it's realm. If the summoner's body is destroyed, but not eradicated, then the eidelon only needs the largest available piece of it's summoner. If the summoner's body is completely destroyed (by a wish, or disintegrate spell, or other means), then the eidelon is banished.
Replaces: This replaces the summoner's spell like ability to summon creatures.
I've seen this...
Resilient Eidolon
Your link with your eidolon is strong enough that it can remain with you for a short time after you fall unconscious or are killed.
Prerequisites: Eidolon class feature.
Benefit: If you are knocked unconscious, fall asleep, or are killed, your eidolon remains for a number of rounds equal to your summoner level before it is banished. If you are brought back to consciousness before this duration expires, your eidolon is not banished. If the duration expires before you are brought back to consciousness, your eidolon is banished normally.
Normal: An eidolon is immediately banished when its summoner is unconscious, asleep, or killed.
But I have never heard of what you are speaking of. My search foo finds nothing on it either.
Do you have a 3rd party PDF called Into the Breach: The Summoner? The Paracosmist archetype in that document has the class feature you described.
No I don't have that and I could have sworn it was official Pathfinder material. Man, I know this didn't come out of nowhere.
Either way thanks for the effort guys.
