Anduin Default

Level 10

Lightbomb generally provides an extremely strong threat in teamfights, and should be the default.

Holy Word: Salvation should be considered when there's no good carriers for Lightbomb on the team and the opponent has some fairly predictable, high AoE damage, but don't have a good interrupt for Holy Word: Salvation . This makes the talent exceptionally niche.

Level 16

Renew increases healing throughput by a good amount. Note that Divine Star will also increase the duration if it triggered the basic attacks from Moral Compass .

Glyph of Faith should be taken if the opponent is forcing the pull consistently and their threats are on a shorter cooldown than 70s.

Level 20

Varian's Legacy provides a strong amount of raw stats, and synergizes with the rest of the talent.

Inner Fire provides a very strong amount of defenses and makes it easier to deliver Lightbomb . This should be considered if the Lightbomb carrier is struggling to reliably deliver the stun.

Holy Word: Salvation provides invulnerability to everyone in the AoE except Anduin, which can be extremely strong, but if there's any remotely reliable interrupts on the enemy team it should be avoided.
