I've seen some mannequins or statues with clothes (idk how to call em) in some people houses. Where could I get em and how do they work?

I earn lots of gralats (well for me it's a lot I guess?) but idk where should I spend them? Collecting something? Any tips? Ty!

Sparring. Is it like pvp'ing between guilds? Or between guild members?

There's probably no such item as a prize machine? Where you put item in and whoever reaches it, can take the prize?  

1. Red Barn Furniture - Located near the Revolution building

2. Save them for a head upload, or for an event. Don't waste mney on furniture unless you plan to fully decorate it, as selling furniture only merits 50% of original purchase price.

3.Sparring can be both. In season its mainly singles, and end of season tournaments are held between guilds called the GST for short.

4. Don't really understand your final point.

Hope I helped somewhat!  

The mannequin (Not the statue) is available through christmas gifts.

There is no prize machine. It's only in admin events.
