I like the idea of a new design for amps, and the bonus to the racial spells sounds interesting. However, the all-100 sounds too high, no matter how much it costs. It isn't balanced by the lack of hp/sap boost, since that amounts to 125 of either, which isn't much overall.
Super-zun amps are 96-97 in all but one (depending on your mix of the other bits), so anything purchased shouldn't be higher than that. Maybe have two options, a lower cost but lower performing at all-90, and then a higher cost and higher performing at all-95. The racial bonus would make the all-95 version effectively all-100 when casting the racial spells. (I predict a lot of Zora versions of this being purchased, if implemented) =)
Super-zun and player-crafted amps would still be better, particularly if rubbarn procs, so the min-max player would still go for crafted. The faction amps could be a good fallback if you run out of crafted mats.
