Okay, so I'll admit, this idea is part born out of jealousy, part "I like this model and want more", and part thinking of faction needs. So these ideas sloshed around in the brain for awhile, until I thought up the crazy idea for a Ret specific caster attachment, who addresses some of the needs of the faction (but not the one you'd think) without being too crazy. Maybe. So, here goes.
The Arcanist Engineer
A senior arcanist, who's seen years of service in the Iosan military, from the War of Houses, to the current conflicts at home and abroad. He's a leader amongst his kind, and he both works closely with the artificers of House Shyeel to improve myrmidon design and function, while also supporting casters in the field with his expertise and advanced arcantric tools.
Same as an Arcanist, +1 DEF, five wounds.
Wrench, same as the Arcanist.
Inspiration [Arcanist] (Not strictly needed, but I thought was a neat little extra.)
Sacrificial Pawn [Faction Myrmidon]
Arcantric Tuning (See Caitlin Finch)
Arcane Reservoir (When this model makes a Repair roll, it may effect Force Field boxes)
Elite Cadre [Arcanists]: Arcanist solos gain Arcane Reservoir
Arcane Sympathy (When a Friendly Faction Myrmidon spends a focus points to regenerate it's field boxes while within this model's CMD range, this model's attached Warcaster heals d3 points of damage)
SO... is this too crazy? I think it's a neat idea for something that's an alternative to Sylas, and also provides a bit more focus support for our jacks and casters, which is really something we lack. Also, I like Arcanists, and feel more of them would be awesome. He miiiight be too crazy to go with a future dedicated jack caster, but then again who knows when or if we'll get anything like that. But yeah, Arcantric Tuning. Hot damn do I want this. We need to steal Finch and put pointy ears on her...
