How do I change my character's size?

There is a spell/blessing that you can purchase from one of the ancestor spirits that will change your character size for a few minutes. Additionally, you can obtain an item called 'Small Mask' -- which turns your character to chibi size -- for as long as you're wearing the mask.

Or you can use a resize potion. However, you can never determine your size as there are over 4000+ heights.

If you’d like to measure your height, this website will do: http://skykidheight.com/ .

Although it isn’t quite accurate, still does the job.
