Dark Souls

[Pete for President]

I'm thinking of doing a Lone Wolf or a Psychopath challenge: no talking to anyone, or even killing every NPC. That means no weapon upgrading, no repairing, no summoning/being summoned, no merchants, no purchasing weapons, equipment or ammunition and most importantly: no Estus Flask upgrades.

Strategy spoiler
I think I'd go for a strength build and rely on Dragon weapons (though not the special attacks, since I can't repair). I'd start out trying to loot a Black Knight Halberd from the Basin, and if that fails obtain the Drake Sword. After the Gargoyles I'd kill Andre for Artorias' Crest and get the Stone Set. Then I'd set out for Ash lake to get the Dragon Greatsword and Homeward Bone back to Blighttown. That would probably be my main weapon for the rest of the game if the Black Knight Halberd fails, though the Dragon Tooth found in Anor Londo is a good option too. It would be possible to start out as a pyromancer (for the flame, as no talking also means not getting one from Laurentius/Eingyl) and get the Power Within pyromancy to help with the Four Kings and Seath. I reckon it's possible, though the no Estus upgrades kind of frightens me. At least there's always Humanity.
