What is the strangest character you ever played?
One of my favorites was a Duegar Dwarf that was a cleric of Nerull. He had like a 6 charisma most from an ever oozing scar across his face. One of my favorite things to do was to post what he was thinking and have him say or act totally different to his fellow companions.
An example of this would be...One day you shall all bow to my feet begging me to allow you to live...then say out loud. "So who is hurt, I have plenty of healing I can call upon if anyone needs it."
The fun part is that the players would know his true thoughts but the characters did not, so they had to play like everything was fine. Oh those were good times.
