The action bar at the bottom of the screen

To attack a creature, move within range (move to where you can see the attack cursor when you mouse over the creature - a grayed out cursor means you are out of range) and right-click on the creature. You will enter attack mode. Move your character next to the creature and you will automatically begin to attack. In addition to right-clicking on a creature, you may also select the "attack" icon from the Action Bar.

The action bar at the bottom of the screen contains your spells, special abilities, or frequently used items like Food and Water (which give back health and mana Diablo 3 Gold respectively). You can activate these by either left-clicking on them, or by typing the number corresponding to the slot of the spell or ability you wish to use. Mousing over the icons will also show you a tooltip containing the name of the spell or ability. You can also consult your spell or ability books (Spellbook & Ability button on the Action Bar) to get a full description of each ability or spell your character may have. You can re-arrange your Action Bar by clicking and dragging on the icons. You can also add new spells/abilities to this bar as you receive them by dragging them from your Spell or Ability book. You can also place items in the bar for easy activation.
Items that are in your action bar and are equipped display a green border around them so it's easy to tell which of your action bar items are equipped and therefore usable.

In WoW, the higher your crafting skill is, the more wow gold you can earn with the new sets of skills. It is possible to craft and sell gear for huge profits, especially when players are still leveling and willingly give away their world of warcraft gold profits for that gear. The highest demand items are going to be consumables, bags, and crafted gear. The crafting professions include the following ones:lchemy - Alchemists can craft anything in the form of potions, elixirs and flasks but since you can only cast one of these things per fight now and nothing major has been added in the form of new content here, you are going to be hardpressed to increase your profits by much though they will no doubt stay the same.
