Arcanist devotion

[Oknar]

Which devotions are crucial for an arcanist or sorcerer (I barely got Demo skills)? Right now I'm playing with Aetherfire on PRM and Tsunami on OFF. I'm not sure which devotions could benefit my skills. Maybe Rhowan's Crown? Or better Leviathan for Tsunami?

ive been leveling an arcanist cold/lightning with some elemental and aether mixed in lately. so far (only at the end of elite) rhowans crown, bound to PRM, and leviathan, bound to trozan sky shards, has worked really well for me. also picked up turtle for some oh ♥♥♥♥ defense. blind sage would be pretty cool too i think, though with my build i really only have 2 attacks and dont have another one to bind it to.
