So was going looking for sunbros to join me to kill Aldrich (am still lvl 25) and waiting patiently at the anor Londo bonfire with all my matchmaking turn on and waiting for a sunbros sign to turn up. Put on my Aldrich faithful covenant at the same time thinking why not pvp a little.
In about 2.5 hrs of waiting I claimed about 25 dregs invading ppl as I was called to defend against the faithless. Literally every 10-15 seconds I was called to defend the area and stopped once I hit 30 dregs to get all the covenant items.
All my invasions are so hilarious :
1. Most time is 2v1 on my side. Never seen a dark moon or blue sentinel appeared which only makes me conclude that most ppl if not all never put their way of blue sign on.
2. Some times the host just died either killed by mobs or someone reach and killed him before I do (free dreg for me lol)
3. 2 disconnected on me.
4. 1 was a full party of 3 persons.
5. There were couple of instances where it's 1v2 with half the time I won (either I killed him luckily or the mobs does him in) and the other half I got wasted lol.
All in all I roughly estimate I had a 80 percent success rate in getting the dreg.
Seriously fun though when I was ganking someone.
