You must also have completed The Gardens Are In Bloom before you can start this stage of the timeline if you did not do the adventure timeline first.
You cannot do this at the same time as Arid Roots as they share the same node.
You cannot be grouped with someone else that has completed this quest or the worm looking things will not appear for you to collect.
Steps[]
Check Typharush plant of signs of borer beetles in the Gardens of Nye'Caelona at ( -479, -99, -431 ) Copy/waypoint -479, -99, -431, primarily around the trunks of the trees.
Click on the Damaged Typharush - this is a non-trackable white cluster of branches. The bush will vanish and a beetle larva appears on the ground. May need to check several Damaged Typharush before getting the update.
