Ex: In the encounter with the father of the Stag-lord, the druid in the cellar, in the videogame, the druid just attacks with single-target spells and go into melee in a small cell.
In the PF: K it´s a full-fledged druid. He casts aoe spells in the small cell to debuff the entire party, like plant and venom-based spells he is immune to, call lightning, starts summoning bug swarms(immune to entangle, spike growth, etc) and uses meld to stone to hide inside the walls when he is hit. And if he goes into melee, he polymorphs into a beast form before engaging, because he is a druid!
I also have the cell lit with purple faerie fire to avoid sneaking attacks to the druid, just in case.
In fact, he alone is usually harder than the stag lord encounter for some parties if you are not prepared.
