Domain Level increase Question

[habibo]

Ok this a question about the protection domain and i have looked at the others but they all seem to be asking something different than me

it says "in addition, you receive a +1 resistance bonus on saving throws. This bonus increases by 1 for every 5 levels you possess."

So i this increase done in
1,6,11,16 or 1,5,10,15,20 the second one seems like is what it should be since it doesnt say for every five level's after the first like almost anything else

Again this is not about class levels like all the other questions have been assume all cleric or whatever class gave the domain

[Rysky]

The latter, 1,5,10,15,20.

Your reasoning is correct, it doesn't say for every 5 levels after the first.

[Claxon]

Yes, the second is correct.

But do bear in mind it's referring to levels in that class that provide the domain, not total character level. Though I think you are aware of that.
