[quote]I have completed all the adventures at the tower to unlock the prismatic abilities for a new hunter build. The threaded spike melee has not unlocked and I can’t find out how to get it to unlock[/quote] I would suggest double checking all six Adventure nodes within the Lost City hub as they will each list their Prismatic Ability reward if you have not yet obtained it; if the Adventure that awards Threaded Spike somehow didn’t register your completion that specific node should still display it as a reward when previewed.
