I can give you an extra charge raygun 50h (these appear in the shop every so often; I can also hunt you some h/arms to replace the g/arms tommorow), using a quick SNS or SHS at range can net you good hits do to ata glitching, or just NSS/NHS at short range. A hand of justice or asteron striker will have good accuracy for just regular hard attacks, which helps hucast save on ata too. Bombchu is great for flying bosses on hucast too, but you'd have to find someone willing to trade it since triforce event is over. If you have good timing, both boomerang and ultima reaper can actually hit gal gryphon on his flyover, though twin blaze is far easier with its gifoie special just to tag even if it won't do much damage (it's also indispensible on casts for trapping). Technically, there are 2 shields you can access for a boost, s-parts 2.01 (15ata, cast only, normal gilchics at difficult rate), and Gratia shield (available in black paper deal 2, very cheap to get) does work on Hand of Justice to give it +30ata, so even a no hit hoj+gratia would be more ata than a 50h charge raygun, and would be more useful for hard attacks too. There is also the cheap Thirteen armor(available in bpd) and Diska of Braveman combo (13 gives dob 30ata and 50% atp, and good hit dob are very easy to hunt / cheap to trade for), and slicers are very easy to ata glitch. DoB is also not to be underestimated for damage even at max level, it can be a killer ranged aoe weapon on hucast.
