Mastery: Lightbringer beacon healer built around Holy Shock, Infusion of Light, and Holy Power spenders. What the kit brings to Mythic+, the fundamentals for the role, and current video coverage.
Fish for its value on the player who actually needs healing, then spend the Infusion proc on whichever fast or efficient cast the pull in front of you requires.
Which kick, stun, Blessing of Sacrifice, Blessing of Protection or Aura Mastery answers the failure case? Your utility is part of the key's healing plan, not a bonus.
Weave damage globals when the party is stable. A clean Holy Shock into an Infusion-powered cast is worth more than chasing low-value damage into an emergency.
This is an activity playbook, not a static build claim. Start with the current class guide, then change talents and gear around your group, encounter, and rating bracket.
