You cannot smith gold-trimmed at all. You can only obtain the trimmed armor from treasure trails which is a members-only thing.
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 =)
Granite armor is the best armor to wear with 51 defence members.
Proselyte armour.
I'm pretty sure only members can get white knight armor. I haven't been on Runescape in a long time but that's how it was for me. If your a member great, you can probably get it at grand exchange, but if your not a member that stinks.
the only two you can wear are bronze and iron
gold armor is called gilded armor in runescape and is gained through treasure trails
Only if your a member can you and you get from clue scrools lvl 2.
well it depends if you are free and can wear rune but if your member and can wear dragon (be warned expensive!!)
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
smith yourself or become a member and kill fire giants :p.By player killing I think but other than that their is no way to get free rune armor.
Guthix D hide set, Simple.
Full Rune is the current best melee Armour for free to play characters.
