Challenge Mode gear/achievements on multiple toons at once

If you have multiple (linked) accounts, and complete a challenge mode achievement while logged in to a character on your second account, it will also get the achievement.

• Step 1 : Log in to both characters.
• Step 2 : Use 1 character to complete a challenge mode achievement
• Step 3 : Both characters will receive the achievement for gold/silver/bronze

Completing all gold while doing this will unlock all cmode rewards for both characters.

Enjoy!
