after hitting both seventh heaven, and aurum ore nod 27 times between the two(15 hours worth of node hitting today), i think it's safe to say this is not the 'Main' spawn method to spawn gandarewa.

One question for all of you that have managed to spawn him: Are your server's populated enough to kill Dragon blood's DURING the 5am/5pm node, to obtain dragon's blood during the node times?

I dont want to say Gandarewa spawn ISNT relating to the node's, but what if you have to kill blood dragons to obtain dragon blood between 5-5.55am/pm for this to spawn? as server's have stated it's spawned around the time of the node windows.
