Pets: Hunter and warlock pets gain benefits from certain attributes of their masters. The master's Stamina, Intellect, and Armor will increase her pet's Stamina, Intellect, and Armor respectively. In addition, a player's Attack Power increases the Attack Power and Spell Damage of hunter pets and shaman earth elementals, while a player's Spell Damage increases the Attack Power and Spell Damage of all other pets.
Critical Hits: Critical hits do significantly more damage than a normal hit. A critical hit will appear as an extra-large number over the target's head. For all classes, Agility will enhance the chance to critically hit with weapons, while Intellect will increase the chance to critically hit with spells.
Mana Regeneration: You will gain the full benefit of your Spirit bonus to Mana regeneration beginning five seconds after your last spellcast, both in and out of combat. Your Mana will normally not regenerate for the first five seconds after casting a spell, unless you have a talent, ability, or item bonus that does so. Items that grant Mana regeneration per 5 seconds work at all times, even within the five second rule.
Dual-wielding weapons: Your total damage output when fighting with two weapons should be higher than fighting with one weapon and a shield, but roughly equal to fighting with a two-handed weapon. Off-hand attacks deal 50% of the weapon's designated damage. Therefore, it's wise to put your hardest-hitting weapon in your main hand.
Raising attributes and skills
Character attributes are raised automatically when leveling. Attributes rise by fixed values depending on your character's race and class. Skills are raised by performing the skill in question. For example, by attacking with a type of weapon, you will gradually increase that weapon's skill until it reaches its current cap. The same applies to professions and secondary skills. The skill cap for combat skills goes up by 5 per level to a max of 350 at level 70. Profession and secondary skill caps are raised by receiving training from special NPCs.
