Streamline Mirage Acquistion a Little Bit

[Pruinae]

As it is now it can be a little frustating after you've done 30+ runs in the same biome trying to get a specific piece of clothing, but have gotten every single one except the one you were going for.

Some questions that I still have about the way this works:
Does luck affect mirage drop rates?
Do Minibosses have the same or lower chance to drop Mirages as the big ones?
Do Minibosses in the Boss Rot map have a chance to drop mirages as well or in that case is only the big one? 

A way to choose which mirage you want, or to boost their drops rates would be great. Maybe through Lottie? I wouldn't mind spending 30 or even 50 corestones to choose specifically the one I am going for, or just reduce the number of attempts to get it.

The only thing that increases your chance to get a mirage pattern drop is the difficulty level of the hunt you are doing. For the shorter hunts, completing locations under the effects of a teffra anomaly will increase the drop chance of a pattern. For boss lair hunts, doing the highest frenzy level that you can will increase the chances even further. Also, each time a pattern does not drop, your chances to get a pattern drop increases until the next time a pattern drops.

Mirage patterns can only drop from the final boss of a hunt (so the minibosses in boss rot lairs will not drop patterns).
