Everything here is a feature of the W3Arena platform. Ranks, titles, memberships and channels exist in the W3Arena client: in chat, in the player list and on your profile. None of it appears inside any game, none of it changes how a match plays, and W3Arena makes neither Warcraft III nor the maps played on it.

Bought inside W3Arena, not here. The shop is part of the launcher. It knows who you are, what you already hold and what your balance is. This page is the catalogue.
