Galen needs seed pods from a burned twilight fern, which grow near Soul's Crossing (-43, 56, 117), and the regeneration negation draught from Damion Trebatius, a wizard at Incantatory Apex, an arcane project area northwest of Cardin Ward ( -59, 44, -219 ) Copy/waypoint -59, 44, -219.
Gather twilight fern seed pods (6)
Right-click small green bushes and choose to Set Fire to the Twilight Fern
Note, if you do this near an obol shrambler, it will anger them and they will attack you
Pick up the seed pod that drops from the fern
Obtain regeneration negation draught from Damion Trebatius
I must return to Galen Cadabrak in Cardin Ward and tell him the Harrowing Horde have taken over the spires at Incantatory Apex.
