Hatred Gem not showing correct mana reservation.

I currently have a level 7 Hatred Gem. When you hover over the gem itself you will read that it reserves 50% mana. However, when you turn the aura on and hover over the tool tip on the action bar, it reads 70%.

Is it supposed to be like this? It is so hard to find detailed information on all these gems right now so I have no idea.

And no, I do not have any weird items that increase the amount of mana reserved for auras.

Sounds like you're supporting the aura gem with another support gem, which is increasing it's mana cost.

You know what? You are 100% correct.

I just had a look at my off hand where I had it socketed. There happens to be my Conc Effect linked to that socket. Wow. Didn't even notice it.

Thank you so much for solving this issue.

Please delete this thread as I was just not paying attention.

My apologies.
