Never have I sunk more hours into a game than Dark Souls, and most of those hours are spent in PvP. I absolutely adore it, even with it's flaws. Knowing where to go for different kind of invasions is key. Heck, I even love gankers and get a real thrill out of fighting them, so I've made several builds for this purpose only.

A while back I posted this in the "Improve your favorite game" thread, it's mostly PvP related:

I thought long and hard about this, but here's how I would tweak my precious Dark Souls and it's PvP:

Weapons Attachment 39041

Remove regular base damage for elemental weapons and replace it with scaling based on the elemental damage. The scaling part will become the regular damage stat. This way elemental weapons can no longer be exploited by level 1 darkwraiths or abused by players who only dump stats into Vitality or other support stats.

Magic Attachment 39042

Make Wrath of the Gods, Darkmoon Blade, all Dark Sorceries and the Crystal Magic spells cost two attunement slots instead of 1. This also indirectly nerfs the Tin Crystal Catalyst.

Make the Vow of Silence miracle cost 1 attunement slot instead of 2.

The Silver Pendant should ricochet/bounce back the Dark Sorceries rather than just delay them, potentially damaging the caster.

Sorceries should have different casting animations so the sorcerer's opponent can recognize various spells. As it is now, once that catalyst goes into the air you have no idea what to expect (surprise Dark Bead incoming!). Should each (kind of) spell have it's own animation, one could recognize and react properly to avoid the almost out of proportion amount of damage sorceries can inflict.

Increase casting time of Dark Bead drastically and reduce the base damage when fired. While the projectiles fly and spread out, they each increase in power up to the damage they do as they are now. This removes the 'shotgun' effect of this crazy OP spell.

Covenants Attachment 39044

Replace the +-10% level difference limit to invade as a Blade of the Darkmoon by being able to invade any Darkwraith from level 1 to your own level + 10%. Of course, the guiltier, the more hunted you'll be.

Let the Darkmoons be able to invade any non-hollow Darkwraith regardless whether they have beaten the boss or not. This is to counter those Darkwraiths who terrorize areas they have already beaten.

Introduce a Distorted Dragon Eye consumable item to invade Dragon-scale owning players much like Darkmoons/Darkwraiths, rather than rely solely on the duel system provided by the Dragon Eye. Distorted Eyes must be found/bought and are consumable, but can only be used when the player has the Dragon Head activated. Once the Dragon Torso stone is obtained, full-body dragons can invade without limit as long as they are in full-body dragon form.

Optional: give the Dragon Covenant a ring so they are summoned by Kalameet to defend the area leading up to him. These invasions take place after Gough has shot Kalameet in the host's world.
