Current drop rate of the blue schematic for royal gems

i know that the green schematic drops rarely. but since like 2 newest releases of this game i think i never saw anyone drop any of these books.
also did anyone ever got the blue schematic dropped from a chest for lockpicks?
it almost feels like the droprate somehow changed with the newest updates.
so it really may be better to farm 1000 clovers to buy the book

 

I got tired of waiting for them to drop, I bought the 2 recipes, yes, I just bought the recipes and they were dropping me 3-4 days, as with the picking of the game of having spent the clover

 

I got it 4 times in 10 runs yesterday
That is the funny "DSO RNG"

 

I dropped them at the beginning of the year, after a lot of runs (seriously, A LOT!) farming at desert in fatal mode (or maybe higher). And not from chests but mobs. Since then, only 1 more, still in desert.

 

Desert. Seems like it drops there nicely, at least green.

 

I have gotten 5 green drops and one blue. They usually drop in lairs or events for me.

 

okay so aftert farming almost all day for months i got in total 11+ green books dropped and still now blue book. so i just bought the blue book. and OF COURSE after a week im getting the blue book dropped just after i bought it.... i know alot of people said it was rigged that they got the blue book dropped after they bought it. but its 100% rigged!

 

I got mine out of events.. the blue book last Christmas from one of Krampuses Kid cages (or a monster right next to it) and the green book I got back in the spring from, I believe, the Defeat the Undefeatables.

Then I got another Green book from the map right before Herald of the Anderworld while opening eggs (thus another event).


=====EDIT======

OH! Look at that (*looking just below*). I haven't played my DK in almost 3 years now. Huhmm.
