Flyff universe multi-tab spell caster

A helpful tool for the web browser version of the Flyff Universe to cast spells from another tab.

Use this tool to cast your slave's spells from the tab where you play your master character.

Installation

Install the Tampermonkey in your favorite web browser.
Go to this file location and install it. Tampermonkey will automatically detect it.
Enjoy.

In the first tab login into your slave account and click the home symbol on the keyboard. The tool will communicate that it's ready for instructions.
In the second tab login into the master char that you would play. Now you can manage the first account passing the right key combination (key number).

You can disable, previously enabled, spells forwarding without relaunching the web tab by clicking the end key.

Slaves should follow master char. You can do it by targeting the master one and pressing z on your keyboard.
Split your screen between two account tabs. It would give you more control over both chars. Remember this tool is much safer to use than any bot because there is no auto-magic. Still, the game can tell you to react to the captcha.
The good idea would be to set the slave's skills on the ctrl+number combination to avoid clicking spells on both chars simultaneously.
This is useful for using PowerToys "Always on Top" feature so that your slave RM can be on top of your main window character in FlyFF.
