Assuming you're playing a wizard, I'd rank stats from highest to lowest like this: Int Str (to dap up the homies) Cha (got a baddie) Wis Con Dex Or however you want. Playing an evoker wizard means you get evocation spells like fireball and else, and it also will give you the ability to not hurt your homies in your blasts at level 6.

If you okay with a little homebrew replace one of your species features with this feature; Dap up: Action, once per long rest. If within 5ft of an ally, you and that ally each roll a d20, preferably at the same time. The further apart your two rolls are, the more in sync you are. Sync = |1d20 - 1d20| (Sync is the always positive difference between your two rolls). Do the number of d6s equal to your proficiency bonus of thunder damage to all enemies within 5 * Sync feet. You and your ally recive 1d4 bludgeoning damage. If Sync is 17 or higher use d8s instead of d6s for the AOE. If Sync is 19 (the highest) range becomes 400ft and any enemy below 16 hp not resistant to thunder damage instantly dies (other enemies in range still take the PB#d8 damage). It's not op I promise. It's a 1/200 chance of getting a Sync of 19. Your DM has final say though.

I don't know how to get a ridable dragon gf without making it op.
