Purity of Ice Lvl 21 extra cold res?

I have a 20/20 Purity of Ice that gives me +4 maximum cold res
A level 21 also grants +4 max cold per description

But when i change my 20/20 to 21/0 in PoB, i get +5 max cold

Is this a bug?
Dont want to spend 1 Div just to find out its a bug

Im bad at math.

Extra max res happens on lvl 23 for any Purity (except elements)

So if you have +2 to your skill gems, from global mods on gear, local, or Empower support, going from 20 to 21 on gem will effectively give you +1 to max res.
You probably have aura effect somewhere that in combination with the +1 level is enough to get an extra max cold res even if level 21 by itself wouldn't.
ok, bougth it.
didnt change anything.
but also bought ashes of the stars, now i have +5

So its a PoB bug since i have purity linked with determination, malevolence and enlighten.

You are still capped at 90%.

However it would allow you to remove other items providing additional max res

While not entirely impossible, it's unlikely that it's a bug. More likely explanation is that there is a difference between your actual setup and what you have in POB. A single aura effect % can make the difference so maybe check again if both setups really are identical?
Also the aura effect will only change the stats on the character screen, not in the gem description.

Just as I said, you get +5 when hitting lvl 23.

You have global +1 from Ashes and local +1 from gloves, so a lvl 21 gem will effectively be lvl 23, while a lvl 20 gem will be 22, so only +4

Aura modifiers won't affect this. Whether your gem is 20 or 22 is the same for %increased aura effect, as it applies to the +4% max res value (so each 25% increased aura effect will give +1% to mas cold res). However, with a lvl 23 purity, each 20% increased aura effect will provide another +1%, making hitting lvl 23 an absolute priority.

So, no bug here.
