I notice a lot of people post threads about dying to bosses in Last Epoch. Or generally having issues in high corruption encounters, tier 4 boss fights, stuff like that. Tenkiei posted a great video outlining many successful strats and techniques to stay alive. If you like these kind of videos and want him or others to make more, give it a look:
How to Scale your Defenses in Last Epoch (Life, Ward, Low Life) (youtube.com)
The simplest āstratsā are simple, donāt let your hp drop to zero & obey the boss mechanics (helps with the former). And donāt make glass cannon builds.
One of the most important things is to fully understand boss mechanics for T4 dungeons. If youāre not playing an OP build, knowing the mechanics is the difference between living or dying.
Play safe.
Main things for those who dont want to see video:
get resist to 75% to make sure enemies get 0% bonus
get as much %none physical reduction as it applies to dots
get affix + amulet [to have dot mitigation]
socket in sealed affix [dots are removed on pot use]
100% critical avoidance or 100% crit damage reduction
*ideally 30% damage taken is retaliation to enemies if you can get it
twisted heart: for ward generation, or a lot of hybrid health with %ofmaxhp converted to ward each second [low hp] combine this with endurance as you have low hp
Xheal on hit/ spell hit / dot
chance to apply fraility on hit, chance to get ward on hit
damage is dealt to mana before health [can add 1000 effective healh on some builds]
Why? Itās a % after mitigation & I donāt think it can be leached from (but Iām not sure). There are more useful affixes you could get.
Frailty & chill are awesome affixesā¦
I think mobility is an often overlooked defensive player skill. Not all classes can do this, but when I play falconer, I literally NEVER stop moving other to loot items.
This game has the WORST boss fight design of ALL the ARPGs Iāve ever played, and itās very simple to kill them, you can play with one of the gameās 2 builds (yes, the game currently only has 2 builds) ultra ward staker who IGNORE everything the boss does or some flc bomb that hits 99,999,999 and kills the boss instantly
ARPG golden rule:
Skill vs Powerful build
The less you have of one, the more you will need of the other.
Exhibit A:
I just never leave the town. Feels super safe so far.
games 2 builds? please elaborate. Iāve seen so many powerful builds I have a hard time distinguishing the op ones as each class can be great.
This is what is killing players. If you have to do mechanics that isnāt fun and your build is weak. The key is making it to where mechanics donāt matter. You should either kill Julra before her explosion or have a build that can tank it and stand in her purple goop. Same applies to other bosses.
Yeah but then you have to be good.
In other words, dance around little red marks on the floor on an ultra-polluted screen and donāt care about the boss
Yeah, what Iām getting from the replies is that people want a game more like Vampire Survivors rather than one that requires any actual skill.
And no, Iām not advocating for Souls-like stuff.
Me too, but sometimes I run into enemies or aoe and its over. 
Boss fights take repetition. It took me a good 20 tries before I figured out the dragon bombs.
Thatās what the ARPG genre is though. Itās about looking at the mobs they explode and you pick up the loot. The faster and better you are at this = more loot. ARPGs are loot hunting trading games.
D2 is basically this and that game is timeless, also arguably the best ARPG ever made. PoE picked up on where D2 left off which is fast clearing and OP build for more Loot. If it takes too long to get the loot in RNG loot based games you will never get the loot you need.
Are ARPGs like D2, PoE, LE supposed to be skill based? I never knew that. I thought they were power build progression based to explode the content in order to get that Glorious Loot! Most players arenāt looking for skill challenges in this genre. They are looking for loot hunting. Then finding those ultra rare trophy items. Thatās the excitement!
ARPGs are about the loot and builds. The point is making a new build to pick up more loot.
Since weāre talking about bosses, yes for PoE and LE, yes/no for D2.
You need skill to beat ubers in D2 and you need some for other bosses that canāt be face tanked, though there arenāt many of these.
PoE was the game that basically created the one-shot boss mechanics/multiple phases in ARPGs, or at the very least popularized it. Sirus, Elders, Maven, etc, all have mechanics that you need to avoid. That requires skill.
LE just adopted the same trend, though it seems the new pinnacle boss will have a different approach. Weāll have to see when 1.1 comes.
You need gear not skill. These are gear based games not skill based. Then with powerful gear we can get more powerful gear. Itās a loop. Itās a loot hunting game not skill based. If you increase the skill then it gets in the way of loot hunting.
Some people want to slow down D2R and say we want harder content however that gets in the way of loot hunting. If you slow down runs you slow down loot.
This then again depends on gear. My VK hammerdin couldnāt touch T4 julra and is a bad build for that fight. You could argue itās a skill issue. However itās really a gear/build issue and my HH/Bolt pally stand in the blast and goop just tank and spank.
These games are gear/build based and the goal is an efficient powerful build to find more gear and make even more powerful builds. Thatās the point. If a mechanic kills you then you need MORE GEAR.
In these games itās not about can you defeat X boss but how fast you did it. Those become the challenges. Can you āTankā the mechanic. We see these in D2 in not āIFā you can beat Ubers but how fast. Players create their own skill challenges the Devs donāt need too.
This genre is about loot hunting not skill. You find a powerful cool item and then you say ohhh let me make a new build around that. Rinse and repeat.
