In my experience drinking alcohol does not add to strength as I had heard it
would (maybe some warriors, etc - but not clerics that I have seen) - and
you wouldn't want to drink while hunting because it makes you interrupt on
your casting times. It will not affect your wisdom, but the more you drink
the more your intelligence will drop. It is a pretty useless skill for a
cleric and more for fun and roleplay, in my opinion.
