All you need to know about the Holy spec

STAT PRIORITIZATION

The first thing we’re gonna talk about is stat prioritization. My recommended stat priorities would be: 

Intellect>Spirit> Multistrike>Mastery>Versatility>Haste

Intellect= increases spellpower (so gives an increased healing output)

Spirit= increases mana regen(a must have for any healer, especially now)

Multistrike= grants chances to deliver extra heals for 36% of the normal value

Mastery= your direct heals and multistrikes heal for an aditional x%

Versatility= increases damage and healing done and decreases damage taken

Haste= increases your casting speed

HEALING SPELLS

Single target healing spells:

• Heal
• Flash Heal (use it only on emergencies)
• Renew (HoT, keep it on players for sustain)
• Holy Word: Serenity (chakra related, instant heal, best used during medium damage and to apply healing taken buff before heavy damage)
• Desperate Prayer( “oh crap!” ability used for self heal in emergency situations)
• Saving Grace (level 100 talent skill, on the same branch with  Clarity of Purpose and Words of Mending, “oh crap!” ability used in emergencies situations)
• Guardian Spirit( singe target emergency cooldown that increases all healing taken and sacrifices itself preventing a killing blow, avalable only on holy spec)
