What's a good way to get like, unwanted clothing items from other users?

The best way is the broaker, you can have a lot of stuff relatively easily and if you look for somthing in perticular you can just type the name of the object in the shearch bar of the broaker and you will have it ( if the avi is old that may cost you more then the new stuff)

I looked on the broker and everything is 20,000g+ money,
and I only have around 3500. How do I get lots of moneyz easily?

uh ? in avatar held you can get a lot of item for 500g or a little bit more, the part the more expencive is the wings. For getting more gold you may nead some mission pets, it's a pet who is specialized in one type of mission by exemple :

This guy is specialized in Strength for the mission, all his points are used in that competance

The missions will help you to get some item too, i sugggest you to send mission pet for the best mission that way your score will be better and you will get more gold.

How do I get more proficiency points?
It kinda stops at 12...

You get a proficiency point for every 5 levels your pet gets. So the max for now is 12 proficiency points, since the level cap is 60.

When the megazone gets released the level cap will be increased to 75, so the proficiency points would be increased then as well.

Ok, thanks!

Hi, i can be your mentor if you want, i actualy have two projects started so i can help you with that ^-^

That would be so lovely! ^^

I have sat down and gone through the guides, but I'm a very visual person unfortunately. And then you add in the breeding with cousins, grandparents, and uncles/aunts aspects on top of it and it throws me through a loop ahaha. :P
