Guild Wars 2

Does anyone know how to trigger Shadow Behemoth Event in Godslost Swamp? (Queensdale Map)

My suspicion is that it may be triggered by certain numbers of players in the swamp actively killing portals and the beasts they spawn.

I thought it was on a timer? Like every 3 hours or something?

They seem to be on a timer, and when that timer resets, the meta event chain starts up. In Blazeridge you can ask when the shatterer will be up and they’ll give you an accurate number often with 5 minutes of the meta event to start again
