Shaman Attributes

See the main article Attributes. This breaks down specifically for shamans as follows:

At level 70, it takes 40 agility to gain 1% to critical strike chance.
At level 70, it takes 22 critical strike rating to gain 1% to critical strike chance.
Your level's worth of agility will increase your chance to dodge by about 3% (e.g., +60 agility will give a level 60 shaman +3% to dodge).
Every point of agility provides 1 melee attack power (e.g., +70 agility will give any shaman +70 AP).
Every point of strength provides 1 melee attack power (e.g., +70 strength will give any shaman +70 AP).
- This means that every 7 strength provides 1 additional damage per second (e.g., +70 strength will give any shaman +10 DPS).
Every point of strength increases the amount of damage you block with a shield.

Every point of intellect adds 15 mana (MP).
Your level's worth of intellect will increase your chance to crit with spells by about 1% (e.g., +60 intellect will give a level 60 shaman +1% to crit with spells; at level 70 it takes +70 int.)

Every 10 points of spirit regenerates 1 mana per second. This can also be described as "five spirit yields 1 mana per tick" or "2 spirit restores 1 mana per five seconds" (MP5). See also Formulas:Mana Regen or Formula:Mana regen & Shields

Every 18 spirit increases health regeneration by 1 health per second (i.e., 9 spirit restores 1 point of health per tick).
