Mana burn is 100% deleting all mana across all characters, high level or not… I dont remember it being this strong all the time…

Its always been this way.
Monsters with the **Mana Burn** attribute remove mana in the equivalent of its minimum/maximum damage times 4 and deals it as additional damage. Monsters have twice the chance to hit and +20% magic resistance, they don't gain more resist if it would cause a third immunity or increase one of two immunities. Mana burn monsters can prove deadly to players with a high reliance on magic, especially if it is paired with Extra Strong for even more trouble; for all physical classes, having mana leech is useful to regain lost mana while fighting this type of unique.
Due to a bug, melee attacks burn 256 times more mana than intended[[1]](https://diablo.fandom.com/wiki/Mana_Burn#cite_note-1), resulting in emptying mana virtually every hit.
* This is due to a combination of two bugs. The first is because the engine subdivides each point of damage into 256 bits of damage for better rounding accuracy. The Mana Burn code applies this multiplication twice, so all Mana Burn Unique monsters deal 256 times as much damage as they should.
* The second bug that increases this damage to 512 times results from [Hell difficulty](https://diablo.fandom.com/wiki/Hell_difficulty) applying a -100% penalty to all [resistances](https://diablo.fandom.com/wiki/Resistances). This includes the resistance to Mana damage, despite there being nothing that could raise that resistance in game. Thus, all attacks that drain mana drain twice as much in Hell.

Oh wait, so its always been this way, due to a bug that never got fixed?

Even if it worked “as correct”, it would still be close toa full burn. 4x monsters damage so if a monster did 100 damage, it would burn 400 mana in Normal, 560 in nightmare and 800 in hell (due to the hidden mana resist stat being -40/-100)
F$#@.
Alright then… Seems like a pretty OP mechanic to me… right up there with complete damage immunity…
It is a terrible mechanic consider without mana you have no offensive ability. This means melee who get mobbed by mana burn cannot do much if they get hit. It really ruins the flow of the game, much like Iron Maiden did in Chaos Sanc way back in the day.

Basically its either get the following to counteract it:
Damage to Mana
Mana Leech
Mana on Kill
I’d disagree here, usually I’m rocking some sort of leech as melee, and most melee skills have a small mana cost. Even when surrounded, one reg it is usually enough to get enough mana to do my next ability (usually zeal). Then the mana bar plays this up and down game until everything dies. This mechanics SSSUUUUUCCCCKKKKKKSS for casters though if they don’t notice mana burn and take a hit. Mash mana pots and run. ;_;
If anything as stated above, it hurts casters FAR more as remember the damage burned is applied as EXTRA damage to the player. Its how some casters get gibbed once in a while.
Yeah my hammer paladin gets whiped by this all the time. The other problem is, there are TONS of monsters in hell that HAVE mana burn, but its not listed under their name. Is it a hidden mechanic for demons?
Several enemies have mana drain as a mechanic. I believe all of the “specters” have it by default, along with certain champion types have it too.
