My idea was to make a stone wall build. You play the tank roll and spam heal for your team.

Pros-

• High health means you can take a bigger hit and live through it.
• The bigger hits you take, the more damage thorns/reflection will do.
• Life steal can save you if you are being swarmed.

Cons-

• No damage.
• You cant walk.

I believe that thorns/reflect will still be in effect when you are on a horse. I am not too happy with the way it turned out so I was wondering what could make it better.

 

Maybe suppression would be better than moon pool / raindrop because the - mana steal doesnt matter when u dont do damage and you get more thunder defense
