In a rare instance of being inspired to do a thing because I saw an outfit, I finally did manage to finalize Twi's design. As Rarity has the weird 'floating pieces' catalyst, Twilight of course needed a book, so that's how it shakes down. Twi here would probably be a sub dps of some kind with her base attack being a small twibeam, her elemental skill would be a regular twibeam and apply extra damage to wet targets with the option to charge for a larger twibeam, and the Burst would of course be the Twili-hame-ha via two handed finger gun.
I have already designed a couple more of these for the other two characters I always like to draw in series like this, so expect the sisters next.
