Farming Route for the Toxic Seedlings in the Kessex Hills. s usual, the route shows all possible spots, not all of them will spawn at the same time.
You can toggle them in the GW2TacO / BlishHUD menu -> Tekkit's Guides -> Gathering Nodes -> Toxic Seedlings. If you don't see these routes in the game, double-check if you properly followed Installation Instructions. If you still have issues, let me know in the #all-in-one-issues channel on our Discord
