When you kill a monster you get xp and sp from the kill. The number of points that you receive are not always identical but depend of the gap that you are using.
The gap is the difference between your global level and your highest mastery. Let's say that you are level 20 and your highest mastery is level 17, you have a gap 3.
The higher the gap the more sp you get from a monster kill and the less xp. So if you are in need of SP the best way to gain some is by starting gapping, collect a nice amount of SP, and close your gap after the SP farm.
There are sp and xp calculators available one of the best is the nivlam one
