Protector's Stone in helm still worth?

Even though the ED will be bugged, and other stats aside, is it still worth doing this for the minus enemy physical resistance? Specifically for ES/MB Warlock and/or WW Barbarian.

As a blanket statement:
Absolutely.

-10 phys res is quite a bit. Plus the other non-ED stats still work.
And depending on your helmet, you can still make the ED work as well.

Whether it really is worth it for your exact build depends on the build as it can be counterproductive if say you lose a breakpoint that ends up netting you more and that you can't get by other means. Especially for an ES lock in the current state of the game as you can rely on nearly 100% amp uptime, making -res less impactful.
More likely than not though, at least with some shuffling around of other gear, it'll still be worth it.

That said, if you can slot it into your weapon directly, that'd usually be the better way to go.

WW bar, you need to see your monster fight status before use it.

Usually it work good for ww bar when equipment is not so good.

if you see 3%-5% hp remaining in your monster fight. it may help. most case, no effect.

The other scenario is against sunder phy monster. it will help a little bit but you still need spend some time to kill sunder phy immunity.

Also, please experiment it with worst phy Stone if you feel perfect one may help. This jewel is not strong enough. most case, worst jewel = perfect jewel.

How can I make it still work in a helmet?

there is a method, I remember, find some kind of ED or special rare

Helm. it will overwrite bug, but it is not so good.

rare

Helm are weak. there is special rule there but no people use it for some reason...

If you have

Ist or

Lem in your

Helm or

Rune Master /

Tomb Reaver and don't rely on

Burst of Speed then Protector Stone sure is an improvement .

Fade proc is yummy. Additional Experience too. As a hoarder I am working to have 5*

Shako socketed with each type of Stone in my stash. Only have fire and Light ATM. First physical I will get will go right in the

Shako, especially if it will be so-so. If I ever get one close to JP, then I will consider other gear.

It sounds like it probably will be worth it for my ES/MB 'lock since I'll have the free slot in the

Hellwarden's Will anyways. I'm not so sure about my WW Barb because I only really use him for Trav and I have a

Cham in there for CBF. I could move stuff around at the cost of MF or dmg but meh.

The real wonder I didn't think of would be if I put it in my Bowazon's

Giant Skull, would it just be a downgrade? I have a 15% IAS jewel and a 40% ED jewel in there now. I could put in a

Protector's Stone and an IAS/ED jewel, but I'm afraid that would trigger the bug for both jewels (?)
