We actually had spawned Caleb without knowing it, because of his incredible invis, and the fact the sneaky bugger flies around, we didnt see him!
Still willing to run this again tomorrow though!

We had him out tonight. It took several attempts and we believe we spawned him once but sorta erm.. lost him lol
It did take us ages, and it was sort of a let down at the end. Two teams of 8 on the poor ghosty! So he was down quickly. Was worth it in the end.
So he comes out after youve spent far too long killing ghosties (spectral daemons) and he appears at sunset, and then circles the island in the air till sunrise.
Oh and just like busses...we got two at once. One on one side of the isle one on the other. What fun! 
In conjunction with Union Badgehunters, and after several hours of spectre slaying, a small group of us are at a loss as to how to spawn caleb, having tried various versions of the conditions needed.
So, I'm thinking thursday evening, 8pm - Nerva Archipeligo, we arrange a horde of everyones most powerful and badge needed villains and let the slaughter commence!
if anyone has DONE caleb since I10, please please post up here what you did!
See you all later!
TZ!
