Cheat money, then after completing king boar quest in the first town you can buy from that old man unidentified crap. Or just go through the first dungeon (don't go into the boss room at 3rd level) an djust from that I've got around 20 unindentified armor and 20 unindentified weapons, from that I've got the best weapons and armor possible (swordstaff, dark priest robe and MC weapons: light greatsword and blood greatsword).
I'm pretty sure you can savescum, save before gear indentification and reload if you don't get the gear you want
Press Q and W for additional menus, in Q menu you have a skill tree. First few levels there is some balance with MC doing damage and nun just being a heal bot after battle and only defending during the battle, but after getting level 10 or so she has enough mana to use magic in combat, if you then unlock a few skills for her she becomes a monster, almost one-shotting a boss for me once and having powerful AoE. She is much more powerful than MC unless you upgrade his stats directly.
