Potions/items to make yourself bigger (Mostly for mount)

[sarym13]

So just curious what are the main ways to make your character large and ultimately your mount? Like to run around with absurdly large mounts.

So far I use a Tauren illusion toy, and Darkmoon Firewater to increase my size.

There anything else that I can use that stacks with these? Or maybe a potion that makes you larger than what the Darkmoon Firewater can do?

Deffin the World Shrinker + a Tauren illusion is the largest combo I've seen so far. Just sucks that the World Shrinker requires engineering. Is there another item to replace the World Shrinker that anyone can use?
