hi ppl this si a nice guide that you can use when any hack is aviable for one hit ko full hp/mp now the tips that i used to avoid any crash and worked for me since i stayed online for long time until i decided take a break of the game: simple just enter dungeon, while your character is doing the starting poses etc turn on one hit ko 2: after START is gone turn it off. you can play the full dungeon with the hack working. 3. repeat steps 1-2 and every dungeon your run. 4. please remember the hack ill turn off in mid run if: 1: you change any item that changes your attack values (EX: you changed your weapon mid run. 2: if your recive any atk buff or debuff like: auras, random misssion atk buff etc: (any buff that doesnt not change atk or magic atk shouldnt turn off the hack. 3: in case your hack is turned off mid dungeon do this: 1: turn on the hack for around 3-5 seconds or kill 1 mob to see if it turned on. 2: turn off the hack one hit ko, then you can end your run. that should be enough like i said this worked 100% for me and you should be able to stay online as much as you like.
