I guess...if your Mage cast giant form or something to give you ridiculous Str before-hand (or are just a Gish to begin with)...or cast it on the fighter. Otherwise you're likely in the same boat as the enemy mage is; with an 8 str
I personally like to maximize its effects with feats like extra familiar, enspelled familiar, and improved familiar to get a couple ephemeral swarm familiars with spell aimed AMF around them, making them pretty much immune to everything (since they are incorporeal), and able to just sit on an enemy and gradually drain their str to 0.

Familiars: Imp, Ephemeral Swarm x2
Notes:
1. Used Imbue Familiar with Special Ability on each familiar to
transfer the following spells: Each ephemeral swarm recieves two
dimension hop spells, and the imp recieves a dimension hop, a teleport,
and an irresistible frost breath.
2. Normally assumes form of a troll from his persisted shapechange,
this, combined with his veil of undeath and energy immunity spells
makes him invulnerable to damage.
3. Shapechanges into a elemental weird about once every 3 hours in
order to cast foresight on self.
4. Due to each spell aimed AMF active on each ephemeral swarm they are
virtually immune to every effect; since they are incorporeal and
technically inside an AMF, although it technically doesnt affect them.
5. His persisted sonorous hum maintains an image of himself which he
utilizes to fool any enemy without true seeing into attacking the
image while he, and his familiars remain invisible. In order for
someone to attack him they would have to have trueseeing up prior to
battle and get within 120 ft of him without him noticing.
6. Unless otherwise specified the imp always readies an action to
cast teleport on his master and himself if they are in danger.
