I strongly advise duders to try this after a bad day at work, or when feeling generally stressed. Dark Souls, being a naturally frustrating game, lends itself to intoxication very well. For the sake of argument, consider a 'drink' to be 2 or 3 fingers worth of your prefered beverage.
What you will need -
Your standard drink of choice, typically beer, cider or a long mixer (rum + coke) etc.
Your shot of choice, in honor of Giantbomb I find Whiskey to be the best.
A copy of Dark Souls.
A bed/sofa to crash on.
The rules -
Taking a swig on your estus flask = You take a drink
Popping a humanity = Take a large drink
Killing a boss = Finish your drink
Summoning a phantom to help = A shot
Death via enemy = A shot
Death via environment = 2 shots (dumbass)
Death on the way to recover your bloodstain = Finish your drink and take a shot
And finally for PvP players
Win against an opponent = Take a drink
Lose against an opponent = Take a shot
I wish you duders the best of luck, remember, only drink as much as you're comfortable with...by that point you'll be drunk and will carry on anyway.
Feel free to share any other games/things to do alongside Dark Souls, or extra rules you would add. Its been one of those days duders...
