I'm currently working on a homebrew subclass for my next druid.
This is supposed to be a first-line caster + Summoner, who has limited options for the wild form.
I aim to build it somewhere between the circle of the earth and the circle of the lunar druid. So I take Natural Recovery from the earth to restore the Moon's spells and Primal Strike so that their wild form is worth it after the 6th level.
The list of spells that I have chosen is satisfactory for the moment, but the problem I am experiencing concerns the CR CR scale.
Wild forms will be limited to the following forms:
Tank – modeled after the barbarian with rage, animal attack based on a charge and baton damage.
Melee – modeled after a monk with ki points, movements like a standing jump and piercing damage.
Stealth – modeled on a robber with stealth attack, spider climb and damage reduction with reach.
I want wild forms to be more utility-based when you need muscle, speed, or stealth, hence load, movement, and climbing, without changing size or function. So, nothing is smaller than the original size of the PC, and no swimming, breathing in water or flying.
This makes it difficult to select specific creatures to be used as basic statistics, while rendering these wild forms statistically better than wild forms, while keeping statistics low enough to be lower than wild forms in the moon.
It's quite easy, at low to medium levels, if I limit the statistics of the basic beast to CR 2, for example.
But at higher levels, wild forms will have little or no use in combat, as they will only be slightly better than wild forms, but without flying or swimming, and not enough. strong to last more than one or two shots. from a boss fight.
So, what I'm looking for are some good computing ideas to determine HP at higher levels for each of the 3 forms, without simply doubling the PC's HP pool.
I need the tank to be strong and spongy, that the melee be balanced and that the stealth is fragile.
They are not meant to be used to simply trade your class for another. Their attacks are still based on beasts, they just borrow their basic abilities.
