By equipments, I mean the weapons, armors, jewelries, ring, capes, gloves, and boots that you can wear. Some of the equip-able items will increase bounty bay money a certain or variety of stats.

Jewelries won't give you any extra stat unless you enchant it. Rings are a different kind of equipment. They won't give you any extra stat, even if you enchant it, but they will give some special effects, just not statistics-wise. Look above in the Crafting section to see the effect that an enchanted ring has.

You can see your character's bonus stats in the equipment icon. It's right under the weapon and armor icons. Here's what it looks like:

The column under bonus tells you how much that certain attack or defense will be increase or decrease by. Strength and Prayer has its own stat.

In this section, I have listed all of the possible wieldable equipments and their stats provided in RuneScape. The equipments under weapon are the equipments that'll go in the weapon slots.

The equipments under armor are the equipments that'll go in the helm, cape, amulet, body, shield, leg, glove, or boot slot. Rings and ranging arrows won't add any bonuses.
