Hey Narcicero, welcome to the LE forums.
Couple of things jump at me at first glance:
Damage: You need to decide if you are a Hit/Crit based build or a DoT based build, you are all over the place and many things you take only scale on portion.
I don’t want to dicate you what you should take, so if you give us a couple of cornerstones, like what is your favorite skill and if you rather would want to go Hit/Crit or DoT then I can give some more targeted suggestions without persuading you.
Survivability: First and foremost you have somany points in the Sentinel base Tree and have not maxed some of the most potent Void Knight Passives.
Abyssal Endurance
Abyssal Fluctuation
World Eater/Unending Hunger
Doom Knight
Dark Maw
Eternal Form
You have no points or just very few in these.
Also you only have minor leech from the passives and only a Spell Leech Blessing. You should get more generic Leech from some of the very strong VK passives I mentioend above.
Then, why are you dual wielding? This gives you an incoming damage penalty, but can lead to higher damage. But with the skills you took you don’t really utilized dual wielding than much other than Rive maybe.
Depending on whic hdirection you want to Go Hit/Crit or DoT based you should switch to 2H or 1H + Shield.
If you thematically really want to go Dual Wield that is fine and I understand that, but then you need to take extra care for some defense.
Furthermore, you are lacking Health affixes severly. Void Knight is THE Health stacking class together with Druid. Belt, Boots, Gloves, Body Armor and Helmet are the slots with the biggest Health Affixes (Either Hybrid Health or %inc Health). None of the mhave any Health Affixes, except the Belt and that is only Added Health.
You are also using onyl class specific Idols and many of these are all over the place, reducing that to onyl the ones that really benefit your build and use more of the small 1x1, 2x1 and 1x2 idols with good resistances and/or damage affixes can really help you, especially aleviate resistances budget on the rest of your gear if you switch to more health gear.
Here is a planner I updated just based on the survivability for the passive tree, I left a lot of the damage nodes out, because I don’t know yet what route you want to go.
Once yo ustart to also get Health on your Gear all the Health passvies wil lstart to scale you incredibly high.
