So this a fairly bare bones idea for a boss.

We have Xeric, who is an already established powerful mage who ruled Great Kourend. He was killed in a coup but he transferred his spirit into a corporeal body, which granted him enormous power. Currently it's unknown if he's still around or not.

That's already a fairly impressive set-up from what little we know about him. A mage who escapes death and becomes even more powerful than he was in life sounds fairly similar to a lich, which is where I got the name from.

As for the accessing the boss, Im thinking something similar to Skotizo, where you use all those inert Xeric's talismans to access the fight.

Now for the fight, I'm imagining he mainly uses mage attacks and can summon undead minions, standard lich stuff. For an extra mechanic I was thinking he can create different colored barriers that reflect certain kinds of attacks, kinda like the Dagannoth Mother. Purple for Magic, Red for Meele, Green for Range.

Like I said its fairly bare-bones for a suggestion, but I think this could be a fairly cool boss that would expand on some of Zeah's lore and give us a use for those inert talismans.

I'm also open to ideas and criticisms from all of you. Thanks for giving this a look.
