With information such as:
Highest amount of dmg dealt at certain lvls by a well.
Highest amount of ee required charm in order to be effective while doing a well.
Stat placement.
ect.

Does anyone know if there is such a guide?

it all depends on your budget and what you want the success rate to be

If there isn't one there, there probably isn't one.

But for a hardcore weller, you definitely want to have AT LEAST 50 vitality.
Be careful when dealing with heavies, since they can easily hit you for 2k +

With less intelligence, you'll need a more effective charm just to be safe. 150 - 180 maybe? And same for a heal charm
It will cost a pretty penny, just a warning.

PM me with any further questions.

I would actually not recommend a casting char to well with on HC. Imo, it's much safer to use a hybrid character w/ an EE armor. You'll likely be more successful with mediocre gear and charms like Seven is describing would cost you 25k each at least on HC.

Grab 100ee+ Weapon/Armor/Heal and 40 stat charm and you should have a passable success rate. Just make sure you stat enough Vit and Dex and you should limit your risk of dying.

Feel free to PM me if you need any more info

All very helpful Ty

Probably your best bet. I do wells on caster mage. But I have gear worth a lot.

I would shoot for 90-100 dex on your chars with the EE armors.
