Once it is in your inventory, just click on it, or right-click and choose the "wear" option. If the armour is in a box ("set"), you have to talk to a Grand Exchange clerk to change it for its pieces - right-click on Grand Exchange clerk, select "Sets", right-click on the set in your inventory, select the option to exchange it for its pieces.
Granite armor is the best armor to wear with 51 defence members.
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.
well it depends if you are free and can wear rune but if your member and can wear dragon (be warned expensive!!)
the only two you can wear are bronze and iron
Members: granite armor Free players: rune armor
The best armor to wear in Runescape I would say is Bandos, mainly because a nice combination on Strength bonuses with Defense.
gold armor is called gilded armor in runescape and is gained through treasure trails
u have to be 40 in defense for rune armor and 40 in attack for weapons
It is either platebody or chainbody and you wear it to be safe and it helps when you are fighting agressives because it lowers the damage.
You can't trim armor on RuneScape if someone tells you they can trim your armor don't give them your armor they are scammers
If you are a member on runescape them you should get Guilded Armor or Gunthix armor. If you are not a member i suggest that you get Rune Armor. (Gold plated armor dose not change the strength of the armor at all) Hope This helps =)
There is no "best" armor in runescape, but armor such as the "nex" armor (Torva, Virtus, & Pernx) are some of the more elite types. Nex armor is dropped by the monster Nex in the gwd.
