1-12
Before the wand carries
Buy or craft a Lesser Magic Wand as early as possible and use small Smite casts before it is ready. Train Power Word Shield at 6 for harder fights, then replace the first wand with Greater Magic Wand at 13.
12-24
The cheap loop
Put Power Word Shield and Shadow Word Pain on the pull, then let the stronger wand finish it. Use Mind Blast when damage needs to arrive quickly and keep Psychic Scream for open ground. Spirit Tap rewards the killing blow and reduces how often you drink.
24-40
Utility arrives
In dungeons, use Dispel Magic and Cure Disease before the healer is forced to recover the same damage twice. Use Fade after healing draws threat. Cast Mana Burn after the tank has secured the pull and the group has time to control the caster. Dungeon gear can carry the healing set through this bracket.
40-60
Caster density
Power Infusion at 45 strengthens spell damage and healing for fifteen seconds, so use it before the emergency heal or damage window begins. Caster packs become more common after 50. Choose routes where elites remain optional and Psychic Scream has clear ground.
