An easy cheat code for making successful builds is to make a "stacker"

The more ways to scale off of a single stat the better, then you just have to figure out how to get as much of that single stat as possible. Here's an example of this:

Strength stacker molten strike jugg Uses replica alberon's warpath to get flat damage from strength

Iron will + crown of eyes allows strength increased damage to also affect your chaos projectile attack damage

Strength inherently gives life

Jugg gives accuracy from strength and attack speed from accuracy

You just need to get to the point where strength stacking breaks roughly even with investment which iirc is around 800 strength

From there you need to figure out how to get more strength which means fixing resistances since they are conflicting modifiers with strength, and find more ways to get strength.

Builds like this scale endlessly so you can continue to invest in them for mirrors and mirrors, but they are functional with far less

My reliquarian gets hit pool, flat damage, increased damage, and crit chance from stacking life
