Metamorphosis allows you to retain faction bonuses from implants (2.0.202.62 Modes Alpha)

[Former user]

To replicate: - Note faction score for Barathrumites - Metamorph into templar squire - Apply custom visage, select Barath - Remove metamorph - Note faction score for Barathrumites (should still be +300)

I tried a few other implants, I didn't notice any lingering benefits other than when the implant is a + on faction.
