I am currently using Sebille as Summoner/Ranger Finese build and some points in hydro to provide healing/magic armor restore. Summoning is the main focus. If you want to go for summoner/ranger, I recommend an Elf. You can skip hydro if you want to give it to someone else, however it combos really well with soulmate.
You can basically create any surface for your incarnate you want thanks to special arrows and flesh sacrifice for a blood surface without worrying about turn order. This means you can deal physical or magical damage with your incarnate/totems (or yourself) depending on the situation.
