I think all minions owned by you or partied with you can receive the Sorceress' Enchant. Mercs certainly can and get the bonusses on their stats screen. Golems get the animation but there is no way of knowing if they get the added AR and fire damage. So without testing and I can't think how to do that or reading the code and I can't do that... my guess is yes, revives can be enchanted.
Yes the Demon Limb unique Tyrant Club has 20 charges of Level 23 Enchant. This is great as a buff for any level 63 or more characters with the 133 strength to wield it. The Enchant gives a great AR bonus for over 600 secs and about +100 fire damage IIRC. It costs quite a bit to repair per charge so perhaps best used on your Merc or yourself if you have AR problems. Many other rare and magical weapons can have lower level charges of enchant.
I just keep my Demon Limb in the Stash. I find 600 seconds, which is 10 mins of buffed AR is enough for most expeditions. You could keep in the cube or even on the weapon switch since it does fair damage and has some reasonable mods for a back up weapon.
AFAIK only weapons, orbs and staves can get the enchant charges so you're a bit stuck.
I intended to make an enchant sorc that uses an Eternity weapon(revive charges). But it seems no one is sure about the enchant-a-revive thing. I will just bump this thread a bit for some more responses.
