If you just aiming 1-50 floor, you can buy:
Weapon:
Quarple kingbird knife 320m (assume each AS card 80m)
Shield:
Resistant valk shield 96m (32m valk shield+64 m hodre card)
Armor:
Holy Armor and Undead armor. holy armor can protect you from either waterball or jupitel thunder from 1-35 mvp. undead is needed when fighting orisis except you want to die very badly.
Kirin armor 80-100m can be good investment.
valk armor is best because impossible to break by some naughty mvp. you can put peco2 card, if you think elemental armor is for baby.
Garment:
+airship cloak (from instance)
or
whatever you want.
put it with raydric card 30m
Acc:
2 Hurt Mind. 6m (3m each)
2 Urs seal sp 250 180 (90-100m each)
SHOES:
only use TEMP DEX with ea4 if possible buy with SoL enchant for endgame purpose. you can create your own or buy from other. the important is delete your fix cast. if you think fix cast isn't matter buy gray wing shoes or just use variant shoes.
if you aiming higher you need:
+ +9 FAW ea10 2b
+ +7 Tae Gyoo ea 5 ea5 double kingbird 1b
+ Valk shield with alice card 400m
+ Red baby dragon hat. 2b
+ temporal ring
+pdm
or change your build to hybrid. since it nearly IMPOSSIBLE to solo Valk. (i don't say it impossible but seriously she just spammed earth quake on you).
