I’ll have to warn you right off the bat, if you are looking for an extremely overpowered class “flavor of the month” so to say, this won’t be for you.
Yes It is capable of completing SR 75 and doing somewhat respectable gladiator 150-170 runs but not as good as those “S tier” classes.
I jumped on Sentinel after facetanking with Warlord so I had to adjust my gameplay a bit. This build is not very easy to play,
you have to reapply posion, curse, keep your Righteous Fervor, run around like a maniac and squeeze as many aegis of menhir as humanly possible at the same time,
more on that later. Also there are some boss combinations that will fuck you up and you really can’t do anything about it.
However if you play well or you got easy mutators you should be able to somewhat consistently farm SR 75.
I tried different variatons of Sentinel with bloody pox and doombolt acid modifiers even vitality one but they were all inferior to this.
That said, it’s not flawless and improvements can be done.
Thanks to ya_ for optimizing it a bit.
G4 variant with 1 green item - Low stun duration reduction.
G5 variant with 2 green items - Capped stun duration reduction.
Second one is obviously better, but harder to get and it makes it easier to counter stun since you can’t afford to stay still for a long time.
Video of me doing Shattered realms 78 and 75.
As you probably noticed you don’t have elemental resistances capped in base form. To fix that you have to keep the buff from Righteous Fervor,
not only it brings your elemental resistances to 80 but it also increases your defensive ability and armor.
You’ll always want to pair it with Absolution skill from relic because it slightly increases your survivability.
However it is true that sometimes you won’t have time to do that, it depends on what bosses you are facing.
Other than than, you keep your Curse of Frailty up, spam Aegis of Menhir and Dreeg’s Evil Eye as much as possible not only as a dmg source,
but also as a heal and lastly use Ascension on cooldown and always keep up buff from Blood of Dreeg ability, it can also works as situational heal due to its higher duration than actuall cooldown.
As I mentioned in my previous build guide, feel free to use AHK script if you don’t want to be bothered by spamming certain abilities like Ascension over and over, I’ll include it in attachments. One more thing, don’t forget to make use of Vire’s Might and Burning Rift, both are great escape abilities with short cooldowns.
