Lesson Drop Listing/Nightbringer

Overview
While battling through your lessons, you will notice that each stage drops a specific set of gems and a bonus item. There are also some lessons that drop card pieces. Additionally, there are items that can only be earned once per lesson by fulfilling certain requirements. One item can be gained by earning an S Rank on that particular lesson and another by receiving a full combo. All stages are guaranteed to drop at least 1 Gem — with the number of gems dependent on RNG (random number generator) — as well as some amount of Grimm.

How much Grimm you'll receive per battle will depend on your battle score as well as what lesson the stage is in. The higher in number the lesson, the more Grimm you'll earn. Hard Mode stages will drop more Grimm than those in Normal Mode.

Bonus drop items like Watches, Mugs, etc. are not guaranteed and also based on RNG.

The number of Devil's Tree items rewarded for the first time you get Full Combo is 5. The number of Devil Points obtained by getting a S rank or a Full Combo for the first time are shown below:
