Looking at the table, you will see that beside each attack style, it says what it trains. This is pretty self-explanatory, IE a "defensive" attack style will train defence XP, and an accurate trains attack. To end the question that many people wonder, "how do you get constitution XP", you get it by dealing damage to an gold rs opponent. The table there pretty much says all you need to know about the attack styles.You can buy runescape.
Runescape Guide for Crafting
Jewelry is a huge part of the Crafting Skill. Most of the things that are made in Jewelry section requires a cut gem of your choice, except silver items(Runescape Gold). You don't have to put a gem in the rings, necklaces and amulets you make, but if there are no gem, it will be useless.
The Gems
Gems are used in Rings, Necklaces and Amulets. When you enchant one of these items with Magic, the item will get a special power. Doesn't apply to all necklaces.
