Thank you! The Xilef encounter was very rushed at the end of the jam. I intended it to be like Mirror Image in that once you hit one, its obvious who Xilef is and subsequent attacks for that round can be targetted reliably.
The Cyclops key can be burgled off him with some care, though I should have been specific about how that particular challenge should be resolved in order to make it something to scratch one's chin over. I wanted to make sure thieves had a lot of good moments, and this was intended to be one of them. As for telegraphing the medusa, no he just likes turning into a boulder, which I'm realising is confusing that they're unrelated. I also think there should be dedicated telegraphing of the medusa in Laconia via the classic "extremely lifelike statues" amidst all the ruins.
In general I think I cut too much explanation to fit into the time and space restrictions, which leads to these ambiguities.
I appreciate your thoughts!
