no heca or anything, just started getting into eg. so looking at mostly buyable upgrades, also floor 100 on nyzule if that helps. my drakes doin 600~1k dmg on birds

Askar Dirs/Aurum Cuisses
AF+1 hands
Zahak's Mail (hey, you said buyable...)
Flame/Light Gorget
Cuchulain's Mantle (especially if you can take advantage of the extra acc, otherwise stick with Amemet +1/Forager's until you can really pump the DEX)
An actual DD ammo

The really big numbers come from being able to push a high crit rate, but you don't have the gear for that and basically need some of the Hecatomb pieces to do so. The above should at least help some though.
