Proving Grounds - scenario for one player where you have to kill everyone/heal your group/tank mobs, and do it for a certain time
Proving Grounds scale your gear to 463
Gear scaling works the same way as it does for challenge modes. Legendary cloak proc, legendary meta gem, sha touched gem and tier set bonuses are all disabled.
In my video I'll show you my talents/glyphs and tactics.. like when I use my bursts and so on. I hope my video will help you, and thank you for watching ;)
