I am familiar with the 5 points at which you can spawn Temperance. As I understand it, you kill a pot at each of these points for a chance to spawn Temperance. This is the extent of my knowlege as far as spawning conditions go.
I've taken my linkshell on a trek to all five spawn points twice now, taking roughly 2hrs each time. Both times we were unsuccessful in spawning Temperance.
My question is, does Temperance move around? Think Jailer of Faith and the way his ??? moves every 30 minutes.
Second question; if Temperance is killed, how long until you can pop him again? If he doesn't move around as Faith does, then he must simply not be ready to spawn.
