2 minions:
1.
Trains hp dex and UC
Elven gears with a CG and a SoC
Assassin crossbow.
Amulet of focus.
2.
Trains GS and AMF
RoS, corn, spell boosters.
AoI
SoD and a BoT
But UC Doesn't seem to be really good, I would prefer having a flat % of your trained UC bonusing your str and dex.
And that str and dex bonus would not get augmented from items but also would be immune to crossbows and EC.
I would also find it really cool to have different fighting combination depending on the difference between your str and your dex.
