Mana Siphon + Life Regen on a Rare boss -- How to Kill?

Been going at it for a while, 10 mins, and pausing game to look for solutions on the WWW and Forum...

I'm regenerating life/es/mana vs. Rare boss with Mana Siphon + Life Regen. No changes to HP at all??

Tips?? On dealing with a trapped Rare with these mods in a confined space arena. Vaal temple league theme ><"?

Either you one-shot him or Immobilize, if you are mele then solution is to swap to ranged

Mana flask with a "% of mana is restored instantly" mod on it is my go to for the purple donut people. The purple mana drain/lightning damage donut only affects you if your on the rim of it, so hugging the enemy also helps.

I think there's some methods of reducing enemy healing/regen, but its usually better to invest in more damage somewhere.

yeah, seems and sounds like more dmg is the answer.

haha, skipped teleport out.

luckily char not HC, and this rare monster is not hasted / followed my hero char.
Yea. Two bad mechanics together. Damage is the only choice.

Mana Siphon is just terrible. It was esp bad in situations where enemies would spawn and it would hit you without any way of avoiding it. The lightning degen was notably deadly to Doryani Prototype users. Problems amplified by enemies being hyper speed.

Regen was added after GGG decided to make Chaos into a notable damage source instead of a form of "True Damage". Before this ES worked fine to punish players for not keeping an enemy engaged. Regen is just a punishment for not getting regen reduction or doing enough damage instead.

Dont worry it can get worse, they can roll with Haste too, so you cant even run away from them

There is a node on the passive tree that reduces life regeneration by 75%. That helped me be able to kill them. So may want to try that.

Yep. Or if you're on the other side of the tree, slot Acrimony in some chaos DOT skill.

Seriously. Hit the monster with a low-level Contagion, then attack normally.
