WoW Classic – Priest Stat Priority
Spirit – This is Priest’s most important statistic by far. Spirit increases Mana and Health regeneration in and out of Combat. It synergizes with the Spirit Tap Talent that doubles the Spirit for 15s after Priest deals a killing blow, which allows him to regenerate Mana quickly without ever stopping for a Drink.
Intellect – Increases total mana pool and raises Spell Critical Hit chance. It also increases the rate at which a character learns Weapon Skills. Very important stat for a Priest, as stacking it increases maximum mana, which further improves his leveling efficiency.
Stamina – Improves your survivability by increasing your total Health pool. This is an important statistic, but it shouldn’t be prioritized over Intellect and Spirit. Stamina loses some of its value for a Priest because of his ability to Shield and Heal himself very efficiently.
Agility – Increases Armor, provides additional Dodge chance and a Weapon Critical Strike chance. Agility will improve your defenses by a little bit, which means that it is not as useless as Strength, but it should be avoided if possible, nevertheless.
Strength – Increases Melee Attack Power and the amount of Damage that a Shield can block (a Physical Off-Hand Shield wielded by Tanks, not Priest’s Spell – yes, everyone knows that but it is still better to clarify, it is the Internet, after all). Priests can’t use Off-Hand Shields and they do not rely on bashing mob’s heads with their Staves and Maces, so this statistic is literally useless to them.
