Rare Monster with Blue-ish Ring-like AoE

I happened to encounter a rare monster with blue-ish ring-like AoE. Whenever I stepped into the ring, I can't move or perform any action that I have to do some piano-button with all flask due to panic.

It's like a fly trapped into sticky liquid glue.

Is that a debuff? ailment?

What is that?

I have stun immunity from ascendancy, maim immunity from jewel, hinder immunity from jewel, and elemental ailments immunity from Purity of Elements.

Sounds like the Mana Siphoner ArchNemesis mod

Enemies in the Aura take Lightning Damage Over Time and lose Mana every second

Thanks! That is the one. I googled for it and showed exactly the thing.
So, based on the description:
- it seems the mana drain is the culprit for being unable to perform skill

- should be able to move using "move only"

- better get inside the ring and slay the monster

I know this thread is from more than a year ago, but this has returned with Ultimatum. Wondering if anyone has figured out how to make it not an issue. I'm running Arakali's, have full ailment immunity, cb, hinder, maim, etc. If anyone has insight, please let me know. This makes me crazy when i get full stopped in the middle of an Ulti...

Get inside and kill it quickly.

I use cyclone of tumult which is taking 6 mana and have -6 mana cost when channeling but I still get attacks stuck because of insufficient mana stuck in this aura. Anyone knows why is that? Is is maybe that it is because actual cost of cyclone is fraction above 6 mana, just not displayed in UI? Thanks

Just stand inside and don’t touch the blue ring and you’re good

The base mana cost is 6, but -flat mana cost modifiers apply after multipliers, such as those from linked support gems. Your skill still costs 1 mana, which you should by able to see by hovering over the skill's icon in your skill bar.

Try taking the other small passive from the Cannibalistic Rite node. That extra % reduced mana costs of attacks should be enough to lower your Cyclone of Tumult's mana cost to 0.
