Ragnarok Online Assassin Cross 99/70 Sonic Blow PVM Build

DISCLAIMER: It will only work with Soul Linker Spirit and Asperio/Elemental Convert and also of course EDP to one shot the monsters that you're after.

First, get another two account with a High Priest and a Soul Linker though I suspect you have the guild buff if so only make one alternate account for High Priest to use asperio on your Assassin(This is for hunting down shadow property/undead property monsters). For other elements such as Fire, Water and etc, use an alternate account for Sage to convert the elemental property of the weapon
