I would like to try and finish the Gathering Proof (Human) quest https://uo.com/wiki/ultima-online-wiki/gameplay/quests/gathering-proof-human-or-gathering-evidence-gargoyle/ as a guild event sometime.
Specifically, I would like to try to get the void crystals (found on Void Manifestations that are summoned by killing Rouser Gargoyles) at the two spawn locations near the Ter Mur entrance. They are below the Crimson Veins spawn, above the Abyssal Entrance spawn and across the lava from the Stygian Dragon Lair spawn.
We've done the Rouser spawn near the Underworld Entrance, which is not bad after leading the mages away.
The two spawns near the Ter Mur entrance are tight and adjoining. Rousers are pretty tough (they spawn RC's), the Gargoyle Mages are easy to kill but respawn fast. I've tried to solo these spawns and earned one crystal after an embarrassingly long time and many self and pets resurrections. I don't think there is a real good place to draw the Gargoyle Mages to.
Should be a challenging event.
