Passwords are supposed to completely ignore level/weapon upgrade restrictions right?
On the one hand, yes. On the other hand it purposely slows down the summon process when the level/weapon tiers between the two involved players are too far apart. Your priority is shifted down. Like, I've had a case where I was trying to item mule to a lower level character that a friend who just started was using and it took 30 minutes for the sign to show up. Works instantly if you're in the same level range, though. The moment I switched to a lower level character, they could summon me instantly.
The DS3 wiki supports this with their summon range calculator page.
Are you talking about the three knights after the? if so then ignore them. they are a waste of time and just light the next bonefire.Dancer
But they drop refined gems.
