Try this on a lower level monster which you can click on them to attack, not right click as that'll be harder. Firstly, mass click on the monster, 5-10 times, then quickly then mass click on your homeport, again mass clicking. You'll notice that you cause damage, but no movement in you character. This can be usefull with DDS Speicals, when swapping to R2H from range, your ment to heal as they almost attack. Feel free to comment / feedback. If you do not understand, please state which part. It does take a qhile to get it.
Umm. I think this is really really useless, and easy to figure out... but good job posting a guide anyways.
