I am not quite sure what you’re asking. So I’ll have a stab at what I -think- you’re asking.
First: Hunter pets are divided into families. Your pet boar is, surprise surprise in the boar family.
Which is good, boars eat everything. Better than average health, normal armour, low damage.
It’s all in the skills.
Skills the boar can learn (and should be kept up to date)
Bite
Charge
Cower
Growl
Dash
These skills is where most your skillpoints will end up going, as you’ll have to catch new boars at higher levels and train your current boar the skills they teach you.
The skillpoints from trainers. Like a flat amount of stamina or armour. I tend to skip, as they cost a lot in the long run, and don’t add all that much.
