@SplamBorgin To get that title you have to play incursions with one of your friends and get friendship bonus with that friend by clearing multiple zones ( for example 6 zones ) and you will we be rewarded with a friendship crystal wich contains
Gold
Artifacts
Incursions revives and potions
and finally the battle realm bestie title
I got that title in my 4th friendship crystal
