Lol you serious? At level 50 I have about 20 mil. w/out any insane spamming of UDs and TMQs.
Try to do as Jocer said, but you can sell UD1-easy gloves without upgrades for 300-400k.
This question gets on my nerves. Same answers everytime. UD1-Find weapons Att. Speed%, Phys Crit%, Eng Crit%, Upgrade them +10 and up. TMQ1 Hard-Find armour, Anti Crit%, LP% On hit, LP Recover. Other options? Get $35. Buy 600 Point Card. Transfer the points to the game. Buy 1 SP reset. Sell for 100,000,000zeni. You can also do TMQ5 Hard and TMQ7 hard and look for the same things. UD's are for weapons.
Now anyone gonna make a new thread about the same exact thing asking the same exact question, even though there's like 20 of these threads (Over Exaggeration) in each forum?
