KOOL TOWN (Krull Crown)

Crown of Possibilities + Krull, Xumuc Occultist nonsense. The key interaction is Krull + Xenan Lifespeaker to give Krull lifesteal and thus negate the downside, at which point every merchant and Twinning Ritual gives a free Grasping at Shadows.

I've gone with a Stranger package to make use of Krull's ability to re-trigger summon abilities - getting extra triggers off Grodov's Stranger, Makkar's Stranger, and Vara, Vengeance Seeker is sweet. Rindra, Infiltrator, Incarnus, Makkar's Listener, and Caiphus, Wandering King could also be interesting options, albeit ones that are a bit difficult to cast. It may be appropriate to swap out all the sigils and Seek Powers for Petitions.

I'm not entirely convinced that a Shadow market with Krull is better than a Time market with Talir, Who Sees Beyond, but definitely seems fun so far.
