Is it better to go wth Rainbow stones on the weapon instead of Perfect skulls?

Also, which mercenary do you recommend hiring?

Thank you

When you say we should MO an item with Physical resistance, are you talking about "Total Character Defense +%"? Because I can't seem to find a MO with Physical resistance.

Also, how much Magic Find do you consider a good amount to have during Mid Game to start getting End Game items?

Ok thank you!

Been trying to upgrade tiered uniques using the "Unique non-sacred weapon/armor + Arcane Crystal + rune → reroll as next higher tier" formula, but nothing is happening.

Any clues if this is bugged or the formula has changed with last patch?

Thank you
