Weird problem with the enlighten support and pride aura

I have a 4-link helmet (Red-Blue-Red-Red), which is currently equipped with "Flesh and stone" + "Enlighten support" + "Pride" + "Blood and sand"

Enlighten support reduces the mana reservation on "Flesh and stone" and "Blood and sand" but not on "Pride". In fact, I have the mana reservation on "Pride" increases up to 62% (from 50% on non-enlighten pride).

Is this intended or a bug?

Need help.

I thik it has something to do with "Blood and Sand".
Try leaving the Enlighten in the helmet, and only socket 1 other thing and check what happens -->
Socket Pride and what is the reservation now. Remove it again and socket the next gem.

Also what stats are on the helmet and are you sure some of them is not affecting aura's ?

I have tried to remove "Blood and Sand" and "Flesh and Blood" out, and left the pride behind with Enlighten, the result was the same as I placed all of them in. For another aura gem i socketed it in, its mana reservation reduced.

I placed the "Pride" into another slot at another piece of armor, the reservation shot up to 92%(?!), sometimes it reduced to 48%(?!). I have checked all of my equipment and there was no stat that increase the mana cost to any gem piece or skill.

Or there are any game mechanics or hidden thing that I haven't known yet for this?

Edit: Here's my helmet stat https://imgur.com/a/RfMWdqM

Ahh now I understand. Your helmet has the mod --> socketed gems is supported by level 18 increased area of effect.

That mod is the same as a level 18 socketed gem -->

That has a MANA MULTILPLIER of 140% so the mana cost will increase.

Can't you move the gems to either your boots or gloves unless they have the same kind of mods.
You should use that helmet with some kind of skill because you can make a 5L skill in that 4L item.

If you make you chars public, it's more easy to help you when I can see your gear.

So no bug here only error 40. :)

I see.

Many thanks for pointing that out, I'm considering changing that helmet so things can go smoothly with the build.

Anyway, how can i make the build go public?

Once again, great thanks for your help ^^
