We still don’t know for sure if Lil Hal inherited the Prince of Heart title or not, but if he did then I believe Heir of Heart because he was finally able to have emotions upon prototyping.

I’m a Mage of Time and Mod A is a Sylph of Breath

That would just create a doomed Arquiusprite assuming the pre-retcon one came over with all the other sprites. And even if that’s not the case what you’re describing would be an ability of a Rogue of Heart which is Nepeta’s class but typically when two people merge so does their classpect (such as Erisol acting as a Prince of Doom, destroying his own doom ie not being able to spritesplode even though he was miserable). If anything, I feel Davepeta will act more as a Knight of Heart. Knights exploiting and protecting their aspect and Heart being an aspect of the self, the soul, the personality and motivation. That’s just my opinion however.

Davepeta’s power level is probably at least nine thousand so they could probably give LE a run for his money but I don’t think they’d win.

They flew there all drunk on trickster magic. 

He exploded on Lowas

I really like them. Davesprite and Nepeta’s personalities blended a lot better than I thought they would. Plus with Davepta going to fight Lord English, Alpha Dave won’t have to.

No, there are no more single tier sprites, he’s stuck that way

I suppose

No, post-retcon davesprite is dead
