Armour prevents damage. The more you have, the better. Type "Armour" to see what you have on, and what you're missing. For Rangers, you should buy all the soft leather stuff in the Guild Shop. Also buy a Conical Helm, as its one of the best in the game. The best thing is that the basic stuff in the guild saves at level 0. Our Nature's Armour spell will provide you with replacements to the Soft Leather stuff. Nature's Armour is as good as it gets.
Gilded Scale (70): This is found is Xereves, you can take a ferry there from Pesvint. It is found off a tower guard. It comes Very Large in size, so have your bird resize it down. Judge excpetional vs blunt/sharp/pierce. Very nice.
Scales of the Alda (90): Its pretty good, but its not as good as a Gilded Scale.
Bracers of Defense (50): These are good, and can be found in the Black Market. They can be worn with gloves or gauntlets.
Gauntlets of Virtue (50): These are also found in the Black Market. Better than soft leather gloves, but not as good as Alligator gloves from our Nature's Armour spell.
Silver Anklet (25?): Found in pesvint shop, 2 west and north from the garden square. It is a miscellaneous armour type, has some physical protection.
Nose Ring (25?): Found in Pesvint also at the same shop mentioned above.
Celestral Mask (0): This mask is found in Xereves off a ranger npc. She's not too hard, as long as u run in, run out, hit and run tactics =). It protects against magical attacks only, and no physical.
Bronze Buckler (0): Found on the same Ranger with the mask. It can be worn WITH 2 1-handed weapons, or 1 2-handed weapon. Its really good, if you can't get it, ask a high level ranger to get one for you, or ask me if I'm online. I just found out that it saved on a level 13 (Wolph), so I'm guessing save is 0.
Leather Shift (30?): These are also found in Xereves, off a druid npc. They are easy, and it judges a little bit better than our soft leather jerkin found in guild shop.
Chainmail Shirt (100?): Found in Amador off the Wall Guards. They come in very large size, so have your bird resize them. Better than Leather Shift I believe.
Garnet Studded Swordbelt (100?): Xereves, off a paladin npc. It has a horse with it, so be careful. You can kill the horse first, then the paladin (he will stand by and let you kill his horse).
Armour of Arik (200): Best armour thats available for everyone on the realms. I will have to get one, rainbow enchant it, then see if it is as good as the Rainbow Dragon Armour.
Ring of Armour (50): Found off Umber Hulk in Mithris northeast of Giant Oak. Also can be bought in a shop there for around 1 plat. It is armour (duh).
Coral Ring (50?): Its better than Ring of Armour, and its found on that dreaded place Xerxes. Its off some druid princess I think. Its good till opal ring.
Dragon Ring (50?): Shadow Dragon in Hylar has it. It has no physical protection, but pretty good fire protection. I prefer Ring of Armour to this one.
Opal Ring (200): Found in the Crag of Evil. It gives wearer +1 dexterity. Take it off while casting Dexterity spell, and put it back on afterwards. Will boost our Dex up to 21 (max) =).
Silver Veil (200): Found off same monster as the Opal Ring. This is probably the best mask in the game. Comes with an enchantment.
Swan Cloak (160): Quest item. Its not too hard to get, as long as u know how to complete the quest.
Dark Robe (110): Dickerson Gripes has it in Treeth. It help with hiding, but is pathetic protection. Use Small Red Dragon scales with your Nature's Armour spell for something a lot better.
Oak Leaf: Considered a misc. armour, but I like it cuz it sounds cool =). Get it empowerd to add armour values to it.
Jeweled Girdle/Silver Headband (25): These two items are decorations which have some armour value. They are found in a shop on the east side of Rhone. They are pretty expensive, bring some cash.
