Patrick is an encounter in Fallout. You stumble onto a lonely man named Patrick in the desert who you can ask to sing "Na Gheala Mbeadh" if you pass a Speech check. Listening to the song increases your Charisma by one point. You can meet him again, but he will not sing the song for you anymore.
Appearances
Patrick is an encounter in Fallout. This encounter only happens on Mountain terrain squares on the world map.
Notes
Strictly speaking this is not a special encounter. Unlike the special encounters (which can only be found on Desert squares), this encounter only happens on Mountain squares and is one of the 6 possible encounter types for north and south mountain encounters. Encountering Patrick has nothing to do with the player's Luck. Also unlike the others, this can be encountered multiple times.
Behind the scenes
'Na Gheala Mbeadh' is Gaelic for 'The Light Would'.
