Unistalled Poe2 after another Viper loss on HC

In Hardcore, you gotta play, and decide what to play, differently.
The question for gameplay changes from
"Am I capable of achieving this?"
to
"Is this worth attempting this?"

The second question opens you to a lot less than the first.

Am I capable of killing Viper in one try while two levels below her zone?
Yes.
But that's the question for softcore. And on softcore I'd attempt it.

On hardcore the question changes.
It it worth it for to attempt to fight Viper well two levels below the zone?
No. Absolutely not.
It doesn't matter that it's possible to do.
It matters that the risk of trying is not worthwhile.

On hardcore, don't fight Viper until you are multiple levels above the zone.
Don't fight her until your gear is upgraded well past the point you'd have bothered with on softcore.
Don't fight her until you have multiple poison charms to wear or otherwise make poison not matter to you.

It's not really about Viper.
It's just about what it means to play Hardcore.
In HC you spend more time grinding earlier zones to be a higher level earlier in the game.
You spend more time grinding to upgrade gear, or even obtain specialized gear.

In softcore I'll do "the thing" well at at lower level with whatever mediocre gear I've obtained. If I die I'll try again.
Eventually I'll succeed because "the thing" is something I'm capable of, I just didn't happen to do it in one go.
In hardcore I'm not touching the thing until I've leveled past it and obtained great gear.
That's the mode. That's what you do.

I don't know what progression point you've been fighting Viper at, but the answer to your situation is that you should have spent more time repeating zones back in act 1 and 2 to level up more.

My only complaint for hardcore is that if you die, the character should transfer to softcore of the same league, not to standard.

When you can yolo into the fight 2 levels under the zone with mediocre ssf gear and live to tell the tale - you are ready for HC. HC is not for the people who complain when they die (unless it's to performance issues or bugs, and usually the things that people initially call bugs end up being a "learning experience").

The players who over-level and stomp over campaign bosses like viper in HC usually die in the endgame because they never bother to learn how to fight bosses and rely on bosses/mobs dying before they can attack, or rely on being so over-leveled/geared that they can ignore attacks, or somewhere in between.

They basically do everything they can to avoid learning how to actually fight monsters, and then die to something they will call a "random one shot" because they don't know how to fight monsters in scenarios where the content is juiced up enough that they can no longer circumvent engagement.

The players at the top of the HC ladder have likely died to Viper and all the rest of the campaign content 200 times more than most SC players have ever even logged in. That's how they learn it - when consequences are enforced the challenges and their requirement to be overcome are also enforced, as opposed to being circumvented.

This is also why the fastest levelers are almost always HCSSF players. They know how to play the game in a way that relies the least on gear and levels.

Before someone thinks I'm slamming SC - you can play like this in a SC league because it's really just a mindset thing. All HC league does is enforce a constraint which provides undeniability, so it's usually more satisfying for players to experience. You can experience it in SC if you just enforce it on your self and honestly, that's probably the way most players should start.

The Viper fight is mechanically learnable and can be done by every class. You don't need to be in HC to get good, you just need to borrow a bit of the HC mindset. It's almost always worth attempting the content when your goal is to master the content - that's how you become capable.

OP you can’t be this dumb. This is a troll post surely.

Most of you don't seem to understand. I am not complaining about dying on HC which i did plenty because i was not carful enough. I also beat Viper in 0.2 couple times simply by overlevelling and having great gear. Somehow no other boss bothers me so saying go play on sc is silly and does not address the issue. The issue is the design of this fight is absurd. I guess the question is what type of people you want playing your game. Majority of people who like a challenge but to a certain point or crazy people with no life who sink thousands of hours into the game. I would think from financial perspective it's better to cater to majority but I don't know, I could be wrong. I'm just giving my point of view.

Viper is really not that tough of a boss and her moves are very intuitive. I think it's a well designed fight. Some of the newer bosses from 0.3 have some very unintuitive moves, however...
