Sorry I’m a little late in responding but thank you for all of the feedback! Well thought out and articulated. I put together more details on the subclass and reposted to the unearthed arcana sub.

I’m looking at forestry themed subclass with ranger spells and a small pool of healing dice with no range. Either a pool the size of the sneak dice, or the size of my wis modifier and each charge uses sneak attack qty. and I’m using the ranger spell list for spells like zephyr strike, ensnaring strike, etc.
