Concerning Hurricane

There is one way to auto-hurricane kinda.

When you are using hurricane, while attacking, right click someone else and click 'Report to GM' while that screen is up, youll still attack, try it out, play with it. But, while attacking, you cant type or anything useful. Ive used it sometimes for quick times I need both hands elsewhere (2 comps).

There's easier ways to do it.

Hold Hurricane
Open Inventory -> Grab undroppable item -> Try dropping it
Message pops up saying you can't
Hurricane will lock til MP is drained

Enter Windowed Mode
Hold Hurricane
Click outside of MS window
Hurricane will lock til MP is drained

Anything that brings up a message or takes you out of MS while Hurricane is firing will lock it.
