Hi, i have a question about Ranger animal companion in PoE 2. In PoE 1 of what i remember , animal companion only gain HP and DR when lvl up. Are they got more scale in PoE 2? And, is single-class ranger animal companion stronger than multi-class one?

I suspect they will scale with character level, so they will be equally strong regardless of whether you are a single class or multiclass Ranger.

Ye i am pretty sure the animal scales with actual level and not power level so multiclass get benefit of same animal.
