There is no fast way to get armour, you can just make a set, of if you ask nicely, a player might make you a set you can start off with, it will also depend on how friendly the person is, if the person looks too busy it will best be a good idea to ask someone else.
First way is to buy it at the auction house, second would be doing dungeons or raids, third would be buying them with justice, honor, conquest points...
gold armor is called gilded armor in runescape and is gained through treasure trails
The bestest and fastest way is to Craft Nature Runes.
There is no other way :/
It depends whether u are member or not
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.
kill 1000 lvl 5 goblines
No, but you can purchase trimmed armor from members.
The next level would be rune armor.
Combat armor is for melee while drudic armor is for mage.
The fastest way of getting level 70 Defense would be Soul Wars 50/50, if it's still going.
