Eurmal friends prefer not to fight but when they have to they will use anything they can reach for as a weapon (most of the time it will be a bottle).
Nobody bothers to know if Eurmal friends do or don't have the status of initiates.
There is no distinction between lesser friendship and best friendship.
A disproportionate proportion of durulz (when compared to human populations) achieves the status of friend of Eurmal, learning and using at some moment in their lives Eurmali spells. Notwithstanding, only an handful become "full time" friends.
There are records in different points in time of Eurmal friends employing these spells: Illusions; Become Human Child; Charisma; Conceal; Crack; Group Laughter; Strike.
The important thing is that the spells are neither one-use nor reusable. The durulz learns a spell and uses it. When, in the next FDF ritual where Eurmal is summoned, he wants to regain the spell's usage, he will gain the usage of a random spell, not the one he learned in the first time.
"Once an Eurmal friend was able to enter the wedding of the chieftain of a clan in Sartar disguised by the illusion of a roasted lamb. Next, thanks to Conceal, he exchanged the meat in the dish of the father of the bride with bones. That almost generated a war between the chieftain and the bride's father. Finally he left the feast shapechanged to a dog and taking with him the purses of all Issaries traders present."
