Thankfully my body transformed in perfect synchrony to match my height; my shoulders are broader, my arms longer, my body is wider in general. It's good to see that I didn't become some lanky twig.
What's more, not only my size has changed but also my musculature has developed greatly. I examine my stats and see that I've gained 5 in all physical stats. Since these stats didn't come from levels I can say that they are innate, which means that I'm significantly more fit than your average adult male who exercises, as they were stated to have 10 in physical stats while I have 15 now.
This part wasn't included in the ability description either. Fucking sloppy job, system.
