Builder Mode
From Wyvern Source
What is Builder Mode?
Builder Mode is an in-game mechanic where the player can design their own maps in Wyvern. In order to initiate Builder Mode, you must first be in your home, then either click the Builder Mode icon or, if on the PC client, press Ctrl + B, which will toggle the mode on and off.
Getting Started
To get stared with Builder Mode, first go to your home map. If you are using the PC Client, click the Builder Mode Icon (hammer and saw) or press Ctrl + B, which will toggle the mode on and off.
While in Builder Mode, assuming you are on the PC Client, you will now see a new window overlying the client window. At the top of the window are a series of controls for Builder Mode and at the bottom are the assets you can purchase and place in your map.
