Elder Mythos cultist's get the following ability:
Channel the Void (Su): At 1st level, when an Elder Mythos cultist channels energy, he taps into the unthinkable void between the stars. This is similar to channeling negative energy, but instead of healing undead, this blast of energy harms and devours living beings, corporeal non-skeletal undead, and constructs crafted from flesh (such as flesh golems). This is not negative energy damage; instead, the damage manifests in the form of wounds from supernatural deterioration and rot. A creature that would take damage from this energy can attempt a Fortitude save to halve the damage, rather than a Will save. At 8th level, a creature that both fails the Fortitude save and would be killed or destroyed by this effect is entirely disintegrated, leaving behind only a trace of fine dust. A disintegrated creature’s equipment is unaffected. This ability still counts as channel energy, but it counts as neither positive nor negative energy specifically (for example, the Elder Mythos cultist couldn’t take the Turn Undead or Command Undead feat). For the purposes of feats that require channel energy but refer to what happens if the character channels positive or negative energy, this ability alters the listed effect for negative energy. For instance, an Elder Mythos cultist could use annel Smite to damage living or fleshy creatures with his melee attack.
This ability alters channel energy and replaces spontaneous casting.
The ability alters channel energy, does that mean I can't take the archetype and Variant Channeling?
The way I'm reading it, Variant Channeling isn't an archetype. So therefore, it doesn't count as trying to use two archetypes to modify the same class feature.
