Let’s talk nature resist for rogues in Phase 5.
ps – I have a video version of the below guide here:

Why do I need nature resist gear?
There’s one particular encounter in Anh’Qiraj called Princess Huhuran. She’s a big bug lady that looks like this:

She does a bunch of nature damage things, but there’s 1 in particular that can be nasty. At 30% hp, Princess Huhuran will enrage and spam an ability called ‘Poison Volley’ on 15 people near her. This hits for 2k nature damage per hit and will kill people if you are not prepared.
The typical strategy to deal with this is to assign 15 people close to her to to be the volley targets and these 15 people need to stack nature resist to survive.
As a rogue stabbing/slashing her in melee, it basically means you’re going to be one of those 15 targets. This is why you want to start working on your nature resist gear set.
FYI – the old spam pet trinkets trick to make her waste Poison Volley on pets apparently doesn’t work anymore, so you cannot cheese the encounter with pet trinkets.
How much nature resist do I need?
We don’t actually know how much nature resist we’ll need due to Classic WoW fights being much faster than Vanilla. A rough estimate is 200-250~ buffed for progression, if private servers are used as an example, but we don’t know if those difficulty levels will be the same as Classic WoW.
It’s possible that some guilds may just burst down Princess Huhuran so fast that NR is barely needed, but personally I’d still recommend picking up a set of NR gear to be safe. AQ is a step up in difficulty from BWL raids, so it’s better to be safe than sorry.
What nature resist gear should I get?
There are a lot of options, but unfortunately a lot of them aren’t available until P5 and P6.
Here’s a quick cheatsheet of the best options you can get during Phase 4, but I’ve also listed all the later phase items in the tabs below.
Note: Not every single NR option for p4 is listed in the photo… because the photo would have a billion choices if I did that. I just listed a quick selection of good choices, you can look at the full list below for more options.

Tip: There are a ton of open world drops that end with <of Nature Resistance> that I didn’t list below. For example you might find a helm with 25 NR on the auction house. I’d keep an eye on the auction house regularly to see if you can snipe any cheap world drop NR items.
