Boots: From level 30 , you can OSRS GP put on Snakeskin boots. At 70 switch them to God D'hide boots. If you're wealthy, you can purchase Pegasian boots for the most comfortable in slot footwear.
Necklace - The selection of necklace is easy since there are three options. Firstly you have Amulet of Glory which is an affordable and good all-around neck-slot item. Secondly, there is Amulet of Fury, which costs more, but it's an excellent alternative. Lastly you can get Necklace of Anguish which is the best option in the game but needs 75 levels in Hitpoints as well as costs much. Ring - For the slots with rings, there's not a lot of choices that are viable and you should get Archers Ring if you are able to pay for one.
A special mention is due the Void Knight equipment which can be purchased from the Pest Control minigame. This is a great set that can you can purchase with no gold. You need only 42 in all combat stats except Prayer which requires at least level 22. This set offers very good defense bonuses similar to Red Dragonhide set as well as +10 percent accuracy and damage bonuses that can later be increased to +12,5 percent. It is amazing in PvE when you are fighting enemies with low defence and in PvP because it isn't droppable or destroyed under the level 20 Wilderness.
