i can tell you what i used due our valkyre team times.

that was
mine and
capri's valk gear. i dont have a screen of our bio when full equipd for valk but its mainly like that : here we go
Upper Head: Kaho (20dex for cast, 20int for damage)
Mid: curse lift mini glasses (1int from miniglasses, 2int from ESL card)
Lower: PCB for more def.
Body: +x
HOLY Glittering jacket (to avoid the holy attacks which hit u pretty hard, wihtout holy you can forget valk.)
Wep: DD Djinn ( you ask why DD? you need to throw the AD bottles pretty fast so get DD, djinn is nice cuz of 40 dex, you can put much more to int or vit.)
Shield: +x random GTB guard, and some random Guard ( to switch when u get buffs)
Mant: 100% for DEVI !!! no ray. since you use gtb >>edit: and holy armor << , devi is much better

Shoes: +x sleip of doom ( gets u hughe amount of HP)
Acc: 2 celeb (or brising for our rich ) and 1 osiris clip ( you need osiris if you solo her, to warp yourself fast , so she doesnt heal to much)
yeah and here is our old valk board :
