What do they do and how do I use em?

shards drop random in terror zone, statues drop in tz by act boss

whith shards you terorrize a whole act

with 5 statues you open uber ancients for the jewel

right click shard

Dont kill the wrong ancient last, as i did my first time.

What happens if I do?

What is the correct order to kill them?

Depends on which unique jewel you want. It's best to look up a guide to see which stone you want for your particular build.

it locks you out of being to equip the gem as they deem you unworthy or some lame crap.

You’ll need to find the colossal calculator and input your characters name and battletag + the game name you’re in. It’ll run some functions based off that info and your map seed (from game name) to give you the honorable order.
