Lith might not need to train all his forms but I hope he will, seeing him fight while shapeshifting between his dragon, tiamat and abomination sibe would be epic. Also the elf's genuine interest for new things and her reactions are making me like her and I hope she will stay in the story even after this ark.
Ideally, learning about these new forms will unlock some of their abilities that he never knew he gained as a Tiamat. For example, having the dragons' innate ability to understand and replicate enemy spells at a glance (aka the sharingan) would do wonders to relieve Lith of his reliance on Solus in battle.
Last time he used the abomination form to drain lifeforce it overpowered the others and he had to excessively use origin flames to counter it and return to normal, BUT NOW his lifeforces are one single thing so maybe that means he can effectively drain lifeforce and then use it freely like for unlimited flames or increasing his mass! Iv speculated as much since the abomination transformation and i still hope it turns out to be true!
It was pretty cool to see liths abomination side taking the form of his former self and his beast form, it makes me wonder if he does have kids if they will each take after one of his sub forms.i can imagine the human human side would be rather normal if particularly strong, human abomination might kill the mother in the process of being born, and the human beast Would be your run of the mill emperor beast like protectors kids. that also does raise the question of will there be many distinct sub species of each form, for example there are many lesser dragons for the line of dragons, so if each of liths forms can be considered a parent form how would they break down to form different lesser versions. All of this assumed a human partner as well, with my thoughts being based on a healed Kamila x Lith relationship.
