How to enchant items +15 in Aion 6.2. (It's not easy)

I will now explain how I am getting to enchant my items.

1st - Every day I make all available PvP instances, AD, ID,
Arenas, Harmony and Evergale.
2nd - I do all the Genesis Crystal Camp during the week.
3rd - I exchange all my Genesis Crystal for '' Ancient PvP
Enchantment Stone Chest '' in the city of Lakrun.
4th - I always have to leave item +13 with ancient
enchants and use legendary enchants of +13 forwards.
5º - I leave to enchant everything in a single day.
6th - In this process I do not spend any kinah.
7º - Be lucky.
