I found something trying some stuff with my rogue. Using sherion +8, CHD+8 and dual shio+2, while I was killing dts alone, I did a special hit like ice staff (lvl 42 mage skill) animation. It happend 3 time on something like 2 hours.
So, did you know about that? It maybe slow down in pvp and maybe work with dark vane and imir rings?
