Where to get some monster recipes?

Where can you get the shadow lance, lux knight, mech Dino, grem knight recipes? Btw I am at the snowy place.

all of them are quests, shadow lance is in the main ice castle area, mech dino is with cave quests after you get your first ‘old one arkadion’ and the grem knight is another quest (cant remember that one) a few recipes are overworld encounters like the skywolf (good and easy early fusion monster IMO) which is in the northeastern part of the desert near the exit

Thanks discord!
