heal and infuse are more important than starcall. level it last unless otherwise appointed by your adc. starcall only if you can hit a champ with it or your adc is out of lane and youre defending tower. it will consume too much mana at higher lvls. turn philosopher stone into eleisa's miricle asap to consume and no longer take up inventory. chalice will keep you up in mana also mikael's crucible will grant you a 4th heal and removes stun etc from the target great to save your adc or apc from a team fight. her passive is an aura, support this by buying legion and upgrade it of course. during fights when you starcall on that 2 second cdr it will proc iceborn gauntlet while auto atking champs will slow and aoe them so other can catch and kill them. zeke's and will of the ancients aid everyone ontop of your healing everyone has spellvamp and lifsteal. buy wards often to maintain sight but thats a given.
