=For now you should get a heirloom oak weapon if you could afford (or normal oak is fine too), use it temporary and farm for materials like dusts for lv70 zauharant weapon if you want the hardcore way, while doing hero quests for drakos tower.
=Where to get money : Verglas Ridge F1 spam and sell stuff to npc , use these money to buy better armors and insu scrolls to enchant + soulcraft
=How am I going to level up without F7 : Drakos dust farming process from floor 1 + Verglas ridge spam + x2 weekend exp and other exp buff will do.
=How to build end game item at the same time : I started doing galaxia quest at lv50 and ran daily for quests, by the time I reached lv81 I only needed to buy 10% of total mats. However if need money = sell those daily stones (good money), if not = keep.
