Well, then you get into technicalities of exactly which kind of magic you mean. Pulling things from the Armiger isn't something that's based in magical strength, and warping depends most entirely on the distance of your throw. It's definitely possible to push the amount you warp further than normal, but that's a pushing-yourself-through-exhaustion factor.

Elemancy tends to vary strongly based on inherent magical ability - Ardyn and I are good at it, Ignis is exceptional, some of my descendants were virtually useless at it, Noctis has a difficulty in holding the energy but channels it as well as anyone, and so on. It may be possible to push your limits a bit there, but most retainers are fairly capped by the amount they can pull from whoever they're bonded to; Ignis is the only exception I can name offhand.
