You're a fawn, yes?

Only other deer can cast them on you and you on them.

Since you're still a fawn you must wait 30days until you grow up and can receive permanent masks, antlers, pelts...etc.
For now while you wait try designing a future look here: http://animals-and-all.deviantart.com/art/Style-Your-Deer-166428229?q=1&qo=1

Glad to help a fellow fawn ^-^
