I think it’s very hard to achieve. You can’t have stealth on wizard gears except pet. Even if you find a gear with “stealth” affix, once you jasper it will become another affix. Although, you may consider using a combination of Reduced CD + Epiphany + All Skills + Stealth on Pet.
Well, +5 all skills mythstones only go on weapons, meaning you can get only +10 all skills. Legend affixes also works, but I think they’re only +3 (?) and are found only on certain gears, meaning your build will have some restraints. Yeah, I remember it had cap (10 or 12), check stat page for sure.
Yep. That sounds about right. Permastealth on rogue indeed possible but 40 stealth useful with reduced CD. Vanish maybe but that interferes with your own stealth or stealth procs in general. In other class, well 10 stealth on pet and 2x 5+ all skills in wizard or warrior, combined with reduced CD. but 20 stealth isnt the same as 40 stealth so not permanent. It lasts a decent amount of time.
Oh and 50% dodge to be doubled for 100% dodge. It wasn’t always like this until patch 2.5. Also back in like patch 2,0 when arena was introduced, stealth used to double dmg so it was used too much and when it had longer duration in arena and PvE.
