stfu you need to wait for cds anyway after you finish a 1v1
if the person doesn't have the courtesy to wait until you're ready, which a lot of people don't, it's straight up impossible because combat mode isn't going to end while someone's attacking you.
Half the time and make ALL gear changes impossible in combat mode. If you want to kill faster, use attack gear. If you want to survive longer, use the options you already have. (HP potions, IG, genie, survival skills) Hardcore PK ftw. Go play Hello Kitty Online if you can't handle it.
