Fly Indoors With Toy (Patreon)

The item Abyss Caller Horn:

allows you to fly indoors. To do so you must lag your client-the crude but simple way to do this is to pull the cable out of your modem for a few seconds, a more elegant way is to use a program such as lag7:

Enter the large pool of water the toy creates and you will find your character can swim. When lagging you will find you can fly outside the water - for as much as 8 seconds before you lose connection with the client.

Sadly the toy does not work in instanced content or no-fly zones.

The toy can be purchased with 500 undercoins-this is a currency you receive for running delves. It must be easy to grind this amount because I had this amount of undercoins without even noticing from my limited experimentation with delves. Note that this currency can be transferred between characters-you do not need to earn it on a single character.
