I want to buy monthly enlighten but im not sure i will get summer pack or not. Are monthly packs counting in events? Like event mall or other ones?
How it works?

Any jewel purchase counts towards the jewels needed to collect the summer pack.

However, the "free" jewels you collect each day as a part of the monthly enlightenment pack *do not* count towards the summer pack - only the original jewels that came with the purchase (3,800 in the case of the monthly enlightenment pack).
