I understood that when i do ritualistic/formal approach to Elubatel he seems less caring and helpful, but when i simply direct/request something by a simple daily manner he suprises me with unpredictedly helpful results.
And second deduction was as i underastand; his greatest operational quality lies in social sphere, he operates within my interactions towards goal and if you try to request him for an affair, you maybe suprised by the result. Try angrily yelling him to find you a lover after upsetting attempt at the night club and he perfectly gives an answer the day after by his sense of humor and a little punisment to your manner :p
Lastly, i remember some debate about speaking the intent aloud, but i speak from my mind and i think there is no difference if you have a working relationship with the angel.
