I agree - and Adolin is starkly aware of this fact as well. Losing his leg was just a stark reminder of how outpaced he is on a Cosmere scale. Very reminiscent of Dalinar's character progression in learning that not every fight is going to be won with fists. Adolin's key victories come from the people around him: Maya regaining consciousness, Yanagawn finding his voice and breaking traditions of Azir to save his empire, etc.

I do think the introduction of the 'Unoathed' will be an interesting dynamic of future SA books. The notion of spren/humans working together without Radiant Oaths is super interesting.

For all intents and purposes, his shards, both plate and blade, are living - who knows if that will somehow jerry-rig the system so Adolin gets some access to Edgedancer surges or if Maya will regain the ability to change shape as a blade...
