[3.26] CWDT Ward Loop Scion

1/ I am sorry, I missed something in my first analysis of your build : I didn't realize that you didn't pick Pathfinder Ascendancy for Scion (Flasks gain 3 charges every 3 seconds).
It is Mandatory. Without it, you would need something like 100% flasks charge gained and 110% flask effect duration.
So, if you simply forgot to select it in Path of Building, do it.
Otherwise, you NEED it(see my second point) Find someone to carry you through the labyrinth, DIY or replace your Forbidden Flame and Flesh with Pathfinder instead of Deadeye.

2/ In your lastest PoB, you selected "Careful Conservationist" Passive skill. This increase the effect of Olroth by 5%, meaning instead of having 85% less ward (1213), you have 89% less ward (892).
Your skeletons deal you 840 damage. This is barely below what you can take. If you ever become Shocked, you walk on Shocked ground, you will increase the damage you take from all sources, including your own. Meaning with 892 Ward you are very likely going to die.
I suggest you remove any mean of increasing flask effect : remove "Careful Conservationist", and if your Timeless jewel is different than the one in your PoB, make sure none of the Notable in radius you are using have "Alchemist Genius" added by the Timeless.
Alternatively, you can replace Zealotry with Purity of Element in order to be shock immune.
Ailment immunity is something that is generally achieved with 100% chance to avoid being shocked + stormshroud unique jewel. Abyss jewel can have up to 50% and a magical flask can have up to 55% as a suffix.

I understand that you likely chose "Careful Conservationist" because of the reduced flask charge used. Indeed, with it and your setting, Olroth should work even without Pathfinder ascendancy. But in my opinion, it's a temporary solution.

First check is generally starting the loop in your HO and leave it running for a few minutes to se if you ward ever decrease or break and if your life ever tank.

But in my opinion, you are likely dying because of source of increased damage taken. Shock is the most common but not the only one. Maps mods and Eldritch altars can also lower your ward if you pick wrong.
