So, we're working on sample character sheets for a certain recently concluded mecha anime,
I suppose you're talking about Darling in the Franxx, not like there's that many mecha animes recently concluded and dual pilots only narrows it down.
and we have a suggestion/request: Can there be some more accessible way to get a subpilot? Spirits only, and cannot swap pilot mid-battle. Examples that show up in SRW would be the Big O, Nirvash, Might Gaine, etc.
The obvious thing would be a Super Upgrade (probably quite expensive, and certainly only take once). Other limitations might make sense too, like being restricted to no more than one spirit a turn.
I must confess that's a thing I've been considering basically since this project started. But as you point out, having a second set of spirits is quite a significant bonus and needs a significant price and/or limitations.
Then there's also the bit that it should not really be super-exclusive. There's been gundams with co-pilots in SRW too, like the Victory. I did the Helpful Automatic Robotic Operator feat half inspired in Uso who gets the Haro for extra spirits after all. In SRW J the main character has a subpilot regardless of going with a super or real. In W we have the Valhawk real starter with a co-pilot out of the bat.
So if anything I believe it should be something available to everybody, so probably a feat.
Secondary Subpilot[Pilot]
Most non-combiner mechas have a single pilot, but some have the radical idea of carrying a second pilot to help control the machine. The reason being that the second pilot is quite spirited but sucks at actually piloting.Prerequisites: Must have Cha 13+, cannot have Spirit Regen, Real Rank, Soul System, Helpful Robotic Operator, companions, followers, familiars nor cohorts.
Bonus: You gain a Subpilot built as either a Real Pilot or Super Pilot of your level (or combination), except they don't get their own mecha, must also take Secondary Subpilot except they don't gain any benefit from it and take a -20 penalty on AC and all 1d20 rolls if they try to pilot a mecha on their own. They can ride in your mecha along you but the only action they can take is using their own spirits and cannot switch controls. You must also spend 8 hours every day bonding in some way with your subpilot (chatting, playing, sharing a hobby, mecha maintenance, house cleaning, shopping, etc) outside of combat or they'll refuse to ride the same mecha as you. Failure to spend the necessary time bonding means they refuse to ride in your mecha until you make up for the missing time.
Special: You may take this feat multiple times, each extra one allows you to gain an extra subpilot as above but only one may ride with you in your mecha at a time. Switching them takes 8 hours to properly re-calibrate the secondary controls. The total bonding time doesn't increase, you can bond with multiple subpilots at the same time.
How does it sound?
EDIT: Added bonding time every day to maintain the subpilot(s).
