The way i see it is, when Rachel split, Darky helped her cope and then when there was financial trouble, decided to help with that.
And besides, RAW isn't everything.
If it was, we'd be playing ChartMaster.
It all comes down to gm discretion.
I decided to stick to two because otherwise this is like, "You and what *physical* army?"
Now, what adept powers should i give Rachel?
Well, she needs Improved ability artisan, so 3 in at, or .75,
Improved reflexes 1, 1.5
Pain relief 1,
Living focus 1
Enthralling performance.5
Flexibility @5(if points aren't split) The rest.
