Chest Opening Mastery is legit the best thing in this league

Try it, you'll really like it.

Works best in chest-heavy areas such as Blight (especially Bligted Maps) and Legion.
You know what i hated about blighted maps? Manually clicking on each chest in these clusters, where sometimes there were 13-14 chests in one cluster (Blight-Ravaged with 3x silver anoint).

With this mastery? One proc and entire cluster opens. It's awesome. Please don't replace this with something crap next league.

Add something for attack based builds.

Maybe "magic and rare items from enemies killed by attacks drop identified".
Then set up your loot filter to show you rare mods and voila, no more hideout warrioring for +2 arrows or +1 all skills.

I'd been curious. What's the radius and does it break other clickies?

In my whole time playing I've found 2/3 mirrors out of clickies. Not chests.

What's a clickie? You mean a breakable object?
It doesn't open those. That is handled by a build like Righteous Fire - breaks everything by simply walking through the map.

As for the mastery the radius is quite large. I opened many blight map chests without even realizing it, when the encounter was still going on and some chests starting to popping up. You don't have to be right on top of those chests, the radius is about a third of the screen.

Yea, clickie is an old ARPG term. Chests fall under that category but barrels, corpses, etc.

It's also an old MMO term used for items with on-click skill effects.
