For me, the Arbatel. I love working with the Olympic Spirits. I've had a lot of success with Och and Aratron. Aratron helped towards securing a 1st class degree and Och helped diagnose my mum's broken leg (the hospital phoned to say they missed a broken leg less than a week after I asked Och to reveal the real reason for her leg pain).
More recently Och helped highlight my pitfall of lowballing salaries in a dream after I asked for career help. Phaleg gave me a spark or drive to self-study again, Ophiel helped with learning writing and coding again, Phul helped me discern a dicsign scam the morning after the Ritual, Bethor is quietly helping me grow spiritually in the background, Aratron helped solve and transmute family conflict the morning after.
