WoW Classic – Warlock Stat Priority
Spell Damage – Increases Damage Done by your Spells (you will want Spell Damage or Shadow Damage as a Warlock). This statistic is quite hard to get early, but Shadow Damage items start to appear in the early to middle ’20s and some can be crafted by Tailors. This statistic will improve your kill times by a lot and increase your Damage to Mana efficiency which will minimize downtimes and allow you to use Life Tap less often, which will preserve Health.
Stamina – Improves survivability by increasing the character’s total Health pool. This is a very important statistic for Warlock because it provides him with Health and Health can be exchanged for Mana via the Life Tap ability. In fact, Life Tap is so strong, that Stamina should be prioritized over Intellect.
Spirit – Increases Mana and Health regeneration in and out of Combat. Stacking Spirit allows Warlock to benefit from the 5-second rule more and further reduces his downtimes.
Intellect – Increases total mana pool and raises Spell Critical Hit chance. It also increases the rate at which a character learns Weapon Skills. Intellect loses some of its value for Warlocks because of how strong and efficient the Life Tap can be. It is still a good statistic, but it shouldn’t be prioritized over Stamina.
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 an Off-Hand Shield can block. Warlocks can’t use Off-Hand Shields and they do not rely on bashing mob’s heads with their Staves or slicing them with their Swords or Daggers (outside very early levels), so this statistic is literally useless to them.
