I think part of the issue with Starlight is that the things it gives are things you only benefit from in a limited amount, so the amount it gives doesn't matter that much; the difference between infravision 8 and infravision 10 is small, and the difference between 10 and 20 neglible. I don't have much in the way of suggestions for fixing it, other than something as vaguely as adding a different kind of benefit to it that's more actively useful.

Conveyance is a reasonable generic mobility option.
Void would be a good choice for extra darkness damage, but Angolwen won't teach such dark magics...
Water might be interesting option for Freeze and Shivgoroth Form (though perhaps not useful for a Lich). No minions means that you don't have to worry about friendly freezing from those spells.
Earth could be useful for Stone Wall and Blessing of Felia boosts physical damage.
Frost Alchemy would involved spending two points in useless talents to then get Flash Freeze and Ice Core.
Air would get you Feather Wind, but you won't want anything else in that category.
Meta is a maybe, cos I've never been able to quantify how useful it really is.
Temporal is good for an extra shield and mobility.
Interesting suggestions! Conveyance comes with the class (at 1.2). Since I'm not to 60 Magic yet, I can't see exactly what Angolwen provides so I just started an Adventurer to look through the options and don't know which are available and not. The four categories I ended up writing down were:
Meta: Removing magical conditions is useful, as is a general buff to spellpower. The resetting of cooldowns would be useful for prolonged blasting, and ED Necro has quite a few powerful t2 spells with longish cooldowns (circle of death, the blood barrier). Preventing pets getting hurt in blasts would've been useful if they weren't already immune to Nightfall and (though i suspect it might be a bug) Grave.
Temporal: As you say, great shield, great mobility. That mana cost though...
Void: Embrace the darkness! Also flavorful, which is a nice bonus. But as you say it's not available so...
Arcane Enchantments: Seems like quite a bunch of nice bonuses especially when they're not competing with another enchantment (unlike for enchanter) and won't cost mana. It's notably less powerful without stone alchemy, but you still find enough gems that getting the bonuses of three gems, generally t5 or good t4's, seems like it's worth the points. And runestaff would allow another escape rune of some kind. But is arcane enchantments even available?
I'm not particularly worried about lack of damage given Eternal Darkness' buff to Grave combined with the general usefulness of Nightfall and Sky Fury from being a lich. I considered the elemental ones, especially air as in addition to feather wind, Chain Lightning allows semi-sniping and extreme ranges that my other blasts don't, but it still seems a bit meh compared to the four above.
