So, I have a PC in an Eberron Campaign who happens to a 4th level dwarven monk. We used a point buy system in creation and I happened to have the following stats: Str: 16, Dex: 14, Con: 16, Wis: 16, Int: 8, Cha: 6.
Now I can play low charisma (some say because it is not much of a stretch for me

), however I am a wee bit unsure of how to roleplay a wise, not so bright kinda of character.
So, my query to you, how would you play it? Silent and strong or unintelligent gruff wise ass (if even possible)?
Thanks in advance,
Thud
