As far as I'm concerned, there's an upgrade to TWT that allows you to enlighten your Tiger Warriors as effectively "Ability"-blooded, around a single Ability. And that does the rest of the job. So, for example, if you enlighten an archer around Archery, he gets to be upgraded to an E2-3 demon-tier enlightened mortal who can learn Spirit Charms themed around Archery. Therefore he gets things like "my bow isn't affected by adverse environmental conditions" and "watch me use Principle of Motion to make Archery attacks", etc etc. There's something similar in HAM.
Basically, Infernals make their own demon hierarchies - Solars merely take their mortal followers and upgrade them until they can go toe-to-toe with 1CDs as equals.
(Meanwhile, Dragonblooded Training Charms are Style-based rather than Ability based, so they're notably narrower, and it takes them much more effort to train a mortal into being a face-beating Immaculate monk who's a peer to a demon.)
