Legend
While we're at it...I did brother of the pine....I had a think about the version posted a few years ago which came out before cantrips were a thing....and came up with this....toning it down a bit asa group monster
Anyhow, to start with I believe it is 5E policy to use gender-neutral names for collectives of creatures unless they literally are all of a particular sex, so unless the Brothers of the Pines are literally all men (as if gender means anything to an undead) we should probably tweak the "Brother" to something else, such as like "Child", "Kindred", "Spawn", "Warrior" or "Scion".
Also, will you also be converting the Leader and Jarl of this monster? I think you should, in which case I suggest you need a title for the group and each individual creature.
For exampe, 5e has a family Ghouls that contains the Ghoul (=Ghoul, Common) and the Ghast (=Ghoul, Ghast) in the Monster Manual, and there are many more types in subsequent works.
So maybe something like:
Kindred of the Pines
Kindred of the Pines, Warrior
Kindred of the Pines, Leader
Kindred of the Pines, Jarl
With the Warrior being the CR 1 basic version we're currently working on, the Leader being a 4th-level CR 2 spellcaster and the Jarl being, say, CR 3?
We could also swap out the "of the" and "Kindred" when referring to these creatures in the description and use "Pine Kindred", "Warriors of the Pines", "Pine Warrior", "Jarl of the Pines" and so on.
Also, "Leader" is kind of boring as a name. Since "Jarl" is a Scandinavian title for a high-ranking noble, I would suggest using "Thane" instead. If you want to go the whole hog we could change the "Warriors" to some sort of Huscarl, although since that literally means Houseman (in the sense of a household retainer / bodyguard to a noble) and they live in the woods rather than houses, I guess "Wudcarl" (meaning Woodman) or "Fircarl" (meaning Pineman) would be more appropriate.
Kindred of the Pines
Kindred of the Pines, Fircarl
Kindred of the Pines, Thane
Kindred of the Pines, Jarl
