With the new patch here defeating the templar on hard may be very challenging to your group , but there is a new way to easily beat him. The group MUST have enough damage to kill him before he enraged though.

Here is how you do it: Spread your group out on the platform that you spawn on. Once you do that you choose 1 person to jump down and get the shield. Now here is the most difficult part. Once the person grabs the shield you must have everyone killing the oracles and helping the shield holder out with the harpies that will he spawning constantly. It will take your group a few tries to kill the boss , but this strategy does work. I will try to post a video on how to do it as soon as I can! If someone else can make a video about this before I can I will gladly add the link to this thread. Good luck and have fun with the raid!
