its missing a guide for level 20+ mages so I made a mini guide for you apprentice mage buddies. : ) we slow mages can unite lol jk (im really slow, i wish my mage can be as fast fighter as the warrior)
do these quests: Lowry @ Bailune City Monster Slaying quest - 30 Dragnof rewards: Dragonskin coat (40 spina), 400 spina
Yeah we wanna be 10 really fast and kill those colon (lvl 5) but sadly you need to stick with chatots (lvl 1-4). ill teach you though which level you should attack first depending on level. (my avy didnt upgrade any status upgrade since its useless anyway without magic)
Level 1-5: stick with level 1-2 chatots Level 6-7: stick to level 2-3 chatots, lvl 4 chatots with full rest each turn Level 8-9: level 4 chatots with full rest each turn Level 9-10: level 4 chatots. level 5 colons (with full rest each turn)
the trick is not to press the attack button too much or it will result a miss. it a probabilty hits if you want to attack colons on level 7+, its fine but remember that colon hits between 19-22 hp damage per turn.
