Hello and welcome to the forum. If you are planning on farming your own, you can try the following (for your level)
Weapon
Fast rod- you get this by doing a quest at chat (merchant in bailune). She asked for hot revita, which you get by filling colon bag at ronfa mountain spring. Make sure you bring more than 5, cuz its like a lottery which can give you the rod, a sword (also good for newbie) and sweet nut. It has 45 atk or so, and -20% cast time to make mana wave faster.
Vajra- from gazer in forgotten cave. has higher atk but no - cast time
Armor
Leather coat - you got them from the month right in front of the entrance to mine. It has a nice MP recovery rate.
Add
Arm hat from brosches has +5 Matk
Special
Stick with tilia charm for HP
If you are good at farming I suggest
Weapon- Sauro stick L2
Armor- mage garb
Add- wind-up key
Special- mitten
Each item (except mitten) will cost somewhere between 1M to 2M. If you can't afford to buy boss xtal, just stick HP+600 in all.
For solo mq, at low level ferzen will be tough. But it's not too late to continue once you reach lvl 50, so just lvl up for now.
Also, level up your mana wave. Quest available from fortune teller in rokoko (she's in a building BTW)
