So I guess I created this for nothing ....
Final Fantasy XV
If you want to make money in this game, sell your treasures, just make sure you keep at least 1-2 of each item. Some of these items will be used in upgrading weapons with Cid later in the game.
Increase the potency of your magic and how much you magic you get out of the thingys...w/e you call them.
The magitek troops are weak against lightning so if you combing your magic to over 100 of each element it goes from thunder to thundara and that becomes much more powerful.
Thundaga is the most powerful.
Here's a good way to start with your Ascension grid
I beat the game in 70 hours at lvl 58
I did a lot of side quests and hunts.
I never felt like I was grinding because I was having fun with the quests.
If you want more money, do the quests where the guy makes you take pictures, they're really easy and he pays well.
If you want a lot of xp, do the quests with the lady who makes you collect frogs.
Then sleep at hotels to get X2 XP for $5k or sleep at a motel for 500 for X1.5xp
