What's the best odds of rolling a perfect ethereal runeword, does it matter what difficulty I roll it in? Does it matter what level character I use to roll it on? Any ritual you've have done or heard of that gives a higher chance of perfect roll?

it's all random senor bigpeepee

Really?? So there's no difference from rolling in the cube compared to rolling in the inventory or stash, and the character level has no effect? 😞

pray to a god of choice if that's your thing I guess

All random where or when you roll it

Don't be a retard and read your horoscope daily until it says you're gonna be lucky and on that day roll your runewords. That's how I got my 664 cta and 55 infy scythe.

using 2nd char to drop 1 gold pieces all over act 3, rolling runeword on 1st char, and if its not perfect going to act 3

I pray to RNGeesus and get a perf roll each time.
The other gods are just inferior.

The less you care, the better the roll
