If you find yourself in a situation where you can't get away look for an ally that is low on HP (< 40%) an run towards him because of the 70% movewment speed gain of Salvation.

When attacking walk towards your opponent and use your AA followed by your Starcall. If he runs away to dodge your Starcall he will get hit by the AA. If, however, your opponent turns on you, he will get hit by your Starcall. Even if you get hit your opponent will loose the trade because of the healing effect of Starcall.

Building health typically isn't good, especially in the early game because your Astral Infusion drains 10% of your health and isn't giving you anything.

Healing a tank does a lot more than healing a squishy Champion because it takes your enemy a lot longer to take the given HP off the tank because of his armor and MR (this is especially important in team fights). If, however, an assassin is jumping your ADC to kill him you should heal him.

To ensure that an opponent is also rooted when using your Equinox use your Starcall first. If he is low on HP and tries to run away, throw it slighly behind him. If, however, he tries to get to you, throw it slightly in front of him. Also use Equinox if an opponent is about to Flash over a wall. Furthermore, Equinox is a good tool to save a team mate to be killed by an assassin because you can prevent the latter from doing his full damage load if you throw your Equinox directly on him when he attacks and heal your team mate afterwards (you can also save yourself by dropping Equinox on yourself, followed by Starcall and run away).

Equinox is also a good tool if your team engages into a team fight. It has quite a bit of range so walk up while the team fight is happening and if you don not think your opponents can jump up on you or your ADC throw down your Equinox on the enemy team. However, because of its long cooldown, use it in the best way possible because you will only be able to cast it at most twice during a team fight.

Normally, use your Astral Infusion for healing, then, once the majority of your team mates are below 40% health or one of your team mates is about to die, use Wish (because of its power increase for champions below 40% health).
