Quality Item - Duskblade

Are you tired of being seen on the map all the time and your support is not clearing the vision? Are you always playing assassins and one shot champions? Then fear not. Duskblade is an item for you. There has been threads about this item all over the place but i've got something else. I ain't gonna complain about the item, non the less, i'll give y'all a tip. You know how duskblades' passive is to show you wards? And then goes on cooldown for a while? Well if you haven't figured this one out, you'll be happy that you've came to this particular thread. All you have to do is stand in the bush where you await for your target to complain how broken your champion is cause you one shot them, and while your Duskblades' passive is on cooldown, hold alt and click your duskblade in the inventory then take a quick peek at the chat. If it says duskblade - unseen, you are good to go and delete your next target! If not, it will say Duskblade - Spotted no matter if its on cooldown or not. Have fun folks!
