Mountain of Muscles and Scars + Stoneform + Avatar

I already like hitting stoneform+avatar at the same time to become as big as a tauren. Now theres another size increase talent!

Is there anything else I can use in combat to become stupidly large for a min?

Winterfall Firewater?

There is an exlixir https://www.wowhead.com/pt/item=6662/elixir-de-crescimento-gigantesco. They should buff this talent to 10% increase.

WoD mission table is a great source of giant growth elixirs if you want.

Also, the comments for that elixir on wowhead have lots of other buffs that may or may not stack.

I agree, I wish it was a bigger size increase. It’s a cool flavor addition.
