If I'm understanding correctly, Soul Memory, the collective accumulation of all souls ever obtained, ensures that the players that you meet in multiplayer are of a similar experience level compared to you.
In Dark Souls, connectability was determined purely through character Soul Level. Does Soul Level still come into play or is it only determined by Soul Memory?
I read that invasion is affected by Soul Memory, but I figured it would be silly if co-op was also affected by it and was hoping to find out if co-op was actually based on soul level.
