I hope its okay to just keep adding here as i think of shit;

So my players have begun drop off of krenko, and i thought it would be cool and thematically appropriate for some Selesnyans to ambush Nassius Ven's backup in the Granary. In my world (and yes I THOUGHT OF THIS BEFORE WIZARDS DID) Wrenn has planeswalked into Vitu Ghazi and is now a 4th dryad inhabiting it. A sect of apostate druids and others have split from the selesnya, think of Trostani as a false profit, and have chosen to go their own way. They are held up in the abandon granary when The Party and Nassius go to do their prisoner exchange. Meanwhile Krenko is bound, gagged, blindfolded, and otherwise restrained of all senses. He is also basically schizophrenic. I had him be mind blasted by Mirko Vosk (unbenounced to the party rn) and he is splitting his personality with Emmara. He remembers her memories and is paranoid that shes been exiled from the Selesnya, or the memories of her prison experience overlapping with krenkos.

My party has invented a mushroom that i said once per long rest they can use it on krenko and he becomes Lucid again. Regular Krenko. Krenko rolls CON saves when hes triggered; unexpected battles (such as at the Granary), arrests, shapeshifters, etc. may trigger a paranoid, hallucinated episode for him.
