Absolute care must be taken when it comes to something highly customisable, lest it become a mandatory part of everything via way of becoming overtuned. Custom Tomes are still not quite as balanced as they should be, and I'm of the opinion that mistakes should not be made again in the realm of customisation.

As such, any custom buff mechanic of a kind should be balanced carefully, and properly. A certain combination is too strong and most people will likely jump at that - seen with the power of custom tomes and the usual goal of going for all damaging seeds, for example.

More freedom to differ between characters is ideal, but it should not be down to one single item giving all that variety, for sure. I would prefer a transformation like this to stick a little closer to the demon translation idea that was put forward, with maybe a few extra bits based on what stat is higher, kind of like happens with the Ogata's Waraji, rather than custom tome level craziness.
