If you mean just a normal one, you can get it from Duke Horacio during the quest Dragon Slayer or you can buy one off of another player or from the Grand Exchange.
(myth) Dragon Slayer (Sinh is a shortcut for saying Dragon Slayer)
If you mean in RuneScape, then they are in the Abyss, and the Canifis slayer tower.
dragon dagger
You mean the hard one, Elvarg the dragon. Either mage it(I dont reccommend this as the dragonfire hits 110, 130+ if not equipped with the anti dragon shield) or melee it(the best way). Bring full rune(rune chainbody) and use a scimitar bring lots of food!
if you mean the guy for vampire slayer, he is in draynor village in a house towards the north side.
If you mean runescape like it says as your categories you can get dragon claw drops from certain npcs or you can buy in grand exchange.
You mean the King Black Dragon, I have placed a link below that should take you to a site where you can get the information directly.
If by 'dfs' you mean the dragon fire shield, the requirement is 75 defence.
-are you sure you lost it? it might really be in your bank but you just overlooked it. once i was trying to get an anti-dragon shield from that duke guy but i had one in my bank the entire time -do you mean the colored keys you get from inside the maze? you have to kill the monsters again to get them again -i have no idea visit runescape forums they can help you
There is no such thing as dragonwarrior armor on runescape. If you mean dragon plate armor, you need to have level 60 defense to be able to wear it. Dragon plate armor has good defense bonuses, but it is a little expensive. To get dragon plate armor you can but it at the grand exchange or buy ir from players. Some monsters on runescape drop dragon armor but it is usually a rare drop.
I can't find a monster with such a name in the online guides. Perhaps you mean "rock slug" - those are found in Relleka Slayer Cave, and need salt to finish them off.
