well will give a hint here...
this sword, as well for mage and pall class (since they are different) are on DO since around 6 months ?? dont even remember...
case is that ... we never released it to public to use in game (only on SS from game etc ....)
why?
its simple this what you have inside this DB/client (effects) and those what is in side DB from long time ... its nothing more then graphic effect of *** skill taken from official eo and manipulated by tracks from inside DB and client (smart connection)... but still its useless ... it has similar effect to normal flying (like wings) or like mage rage skill (if this was the one that makes player to fly and kill..)...
so at all way its just effect... thats totally all
You wont be able to fly out of maps etc etc etc = like this skill should work...
so ultimately - it can be used only for small fun = thats why I never released it to all - still believing someday we will be granted by newest serv files
regards
P.S.
about DBs/Client/etc etc sources - there are plenty... and many was given on this forum (just use the search function or scan slowly)...
