Shoot, I was not able to kill a PC tonight even when I wanted to. The mind flayer had the cleric dead to rights. The cleric was on fumes and stunned. All the mind flayer had to do was hit with the eat brain attack with advantage. The player was leaving our group because of real life. The mind flayer rolled a 3 and 4. Then the rest of the party came to the cleric's rescue and there were squid bits everywhere.
