Undead Unchained Eidolon

[Arden Oakwald]

Is there a way to utilize an undead themed Eidolon with the unchained summoner?

The original summoner had a lot of evolution options available from Ultimate Magic, but does anyone know if the unchained summoner can do something similar, or if the undead flavor has just been nixed all together :( ?

Outside of just playing the old fashioned version? Not without playing up the theme and pretending really, really hard. Necromantic Affinity will help a bit, but the 15 Con requirement will be a stretch for any eidolon that doesn't have the aberrant base form.

But yeah. Unchained's subtype system nixed pretty much every style of eidolon that isn't already specifically listed in a sourcebook and it's a little sad for the really oddball concepts like this.
