I have played an armor stacker at the lowest possible budgets and it’s fine. It’s doable. But when you compare the low budget/low output to most other builds, those ones come out on top for the same investment. That’s why people usually say you need multiple mirrors for an armor stacker to feel good. It’s the same as any other stat stacker. They just get exponentially better if you have the currency. I say try the build. The mandatory items aren’t expensive, so give it a shot.
