Any chance of playing with other players after passing SL 200? I know SL 120 is where many people stop mostly due to PvP. Can I still find people to play Co-op with? How about invading through use of covenants and such?
I messed up my 1st character ever and wound up with a SL 229. I can safely say the forest area (both inside and outside the butterfly boss) are very active for both summoning and invading.
I also get invaded in the burg and oolacile township very frequently along with high summoning rates in Anor Londo, Sen's, Archives and ToG, have not checked Izalith or the Kiln but overall your chances for co-op are high.
