Mirage Munitions Basics
Mirage Munitions are an item you can "add" to weapons for a very small upgrade of +2 Attack, and +10 HP per Mirage Munition on it. Weapons can have up to +99 Mirage Munitions at maximum.
You can freely add and remove Mirage Munitions at the Blacksmith at NO COST.
Where to farm Mirage Munitions?
Honestly, you don't really need to actively farm Mirage Munitions. You can only use so many of them at a time (the practical maximum you'll need is 400). Since you can REMOVE AND MOVE THEM AROUND. I get that there's some kind of "excitement" when you first get them, but fight the urge to actively farm them specifically.
Many quests drop this as a bonus, but if I really had to recommend a quest to Actively farm them... Proud Difficulty Pyet-A perhaps (The Automagod Strikes Back)? But, yeah, I don't see a scenario where you would actively want to farm these.
If you have a powerful AFK farming setup, you can get these from the various missions as well. Trust me, you'll have way more than you'll need very soon.
How to remove Mirage Munitions
You CAN remove Mirage Munitions, but it's not that clear HOW. They also only quickly mentioend it at the initial tooltip, haha.
Simply go to the Mirage Munition upgrade screen at the blacksmith, press Accept on the Weapon that has them, and then put the number down - it's that simple.
