Begginer skills question

Hi, I just started playing Diablo II (res) after few decades, and I have a question about skills: if they are not active (and only two can be active), do I still get benefits from puting points in them?

Let’s take paladin as example, and fire resistance. It says “when active, etc” - but do I have benefits when it is not active?

oh, it says “+1 active, +0.5 passive”

Are there other passive skills, for paladin, for example?

only +0.5 passive for each point give u benefits when inactive. if we are talking about synergies its working for ur active skills all the time. u can find the answers in discord channels. official forum has died like this game…
