Mafia 100. Sylvan: Tree of Life.

This time, there was no mention of any clashes, so we can assume that no one was targeted for protection. Then, the second mafia probably sent the poisoner to kill. And as a third action, they checked with the dwarf, since there is no block on the Medusa.

Although, wait. The poisoner would have had time to poison someone. So, either the Medusa killed and was blocked, or the dwarf, who was killed earlier by the elf.
