There's many armor shops they can be located in the following towns:
In Varrock there is an archery shop. It sells arrows, armor for archers and bows and arrows. It is close to the Varrock sewers entrance.
gold armor is called gilded armor in runescape and is gained through treasure trails
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.
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 "Satan Oracle" armor is from a youtube video. It is not part of the real runescape. The user used photoshop or something to edit fake armor onto his character.
there is no armor shop just type in armor combonations.
Take a piece of armor and use an orange dye on it.
Of course it protects you! Certain armor protect more then others.
