I am new with the avatar clothing but what does an avatar outfit do? How do you get avatar stuff? and How do you get backgrounds and wings and stuff?

Nothing special really, its just a fun way to dress up your avatar with more than just the default outfits in the wardrobe.

Four ways:
. From participating in fests via exploring the zone & defeating enemies. Youll occasionally get them from defeating enemies while battling in the regular game zones and/or completing certain tasks in the game storyline (only in the different areas of Astryls Vale in the case of the latter, however), too.

. Buying things from the festival shop with the given fests currency (This hasnt been available for the last few fests/events or so.)

. Buying from other players via trade, auction, or using gold. Youll find other player threads about this in the Item Marketplace forum.

. Buying things from the avatar shop using Diamonds or this new thing called Peerless Tokens.
