You should finish the yalahari quest for the mask, so you wont waste at least 1kk for that, do the demon oak, at that level is a joke to complete, and get the spellbook (150 lvl required) if you have cash use it to buy the royal scale robe is quite a good item it worth from 3kk to 4kk or something like that, for the legs if i was in you i would take the grasshopper ones reasons: cheap as hell and quite good for a mage vocation, is not really smart at your level waste money for just 1 magic level addition, soft boots for mage in my parer are a bit useless so keep the boh, claw of the noxious spawn are useless, so leave the space for a dwarven/time/enegy ring that are way more usefull to finish, the amulet you have is quite a good one for a mage, but if you want get the Koshei one.
