chalice doesnt cut it for morg, her spells are fairly pricely so a larger pool is better than regen, however 1 archangels staff solves both those problems. but morgs playstyle means you need a decent bit of tankage, a frozen heart is a great core item on her. the armour covers the weakness your black shield cant, gives great CDR and more mana to boot. abyssal scepter have good synergy with your your tormented soil and both those 2 items are auras so help the team. for health you want a banshee veil, rod of ages or a soulshroud, but get at least 1.
