Guide awaiting review
1
Farm Argus enemies
Defeat enemies in Mac'Aree at 63.8, 64.6 or at 36.3, 23.6 for a chance at the Barrier Generator drop. The item has a low drop rate, so expect to farm multiple kills.
2
Use the toy
Once obtained, the Barrier Generator will deflect throwable toys like the 
Dalaran Disc, 
Foot Ball, and 
Holy Lightsphere back at the user, applying a one-minute dismissable stun called Holy Retribution.
