The Way In
Open a route into Rata Novus. Earn your Nuhoch Hunting Mastery to continue your story. Speak to Tizlak about the lay of the land. (Hunt chak and talk to other Nuhoch to collect enzymes so Tizlak can craft you a solvent.) Kill chak and talk to local Nuhoch to collect chak enzyme, and then bring the chak enzyme to Tizlak.: x/6 Use the Nuhoch path to find Rata Novus.
Unlike other story missions, you should not try to reach the green star on the minimap until you have earned the Nuhoch Hunting Mastery. The green star will appear on your mini-map even though it is impossible for you to reach it until you achieve the Mastery. Find Tizlak as described below first. From Teku Nuhoch Waypoint, move up and west to find Tizlak. Talk to him. Then just kill plenty of chak until you have enough Chak Enzyme for Tizlak. You'll find a lot of them if you follow the trail southwards and down. Talk to Tizlak again, then follow the path and interact with portals along the way. There are two other ways to obtain enzymes, the first is about the same, but the latter is generally slower than just killing chak: Get Lost Bag for Veteran Nuhoch Stomper From the Veteran Nuhoch Stomper located near Tizlak, head west southwest past the nearby cave entrance towards the Bouncing Mushroom to access the Zintl camp. The bag can be identified by a purple glow. Return it to the Veteran Nuhoch Stomper to earn 2 Chak Enzymes. This is repeatable. After getting the bag and receiving the 2 enzymes, you can log out and log back in to trigger the task once more. Talk to the Stomper again and go fetch the bag—it will have respawned. You can do this 3 times to get the 6 enzymes required, which may be faster than hunting chak. After collecting all the chak enzymes, you can go to the Veteran Nuhoch Stomper to restart the conversation to finish the task. This time you have the Lost Bag in your inventory, instead of Chak Enzyme. Fight Kaxan Kaxan may appear nearby just southeast from Tizlak or far southwest on the ledges leading to a vista. If he's near Tizlak, he'll ask for 2 gold, but give nothing on return, and instead go to the other location. Head west southwest from Tizlak past the cave entrance and past the bouncing mushroom where you'll find a friendly Nuhoch named Kaxan who will turn hostile once you approach him. Fight him to earn 2 Chak Enzymes. Any gold paid to Kaxan will not be refunded after defeating him. Since the area is often teeming with chak, and Kaxan has a large amount of health, killing chak is a much better option than paying him if he's not on the ledge already. Finding the way to Rata Novus Once you have turned in the enzymes, a new green star will appear on the map indicating a round, blue, interactable gateway located behind the Veteran Nuhoch Stomper. Disregard the main map which shows the green star located on a different elevation level, it is in the same area as Tizlak and the Veteran Nuhoch Stomper. Go through the blue gate and follow the green stars on your minimap through the tunnels. Unlike previous missions, the green stars do not show up in the open world, you will need to follow them on your minimap. The tunnels are filled with veteran and normal chak so it is highly recommended using a mount to run past them. All of the green stars are simply points along the path you need to take and they only require you to run through them. The last green star will be located just south of the text "Decayed Hive" on the main map. Unlike the other stars you followed up to this point, this star is indicating another round, blue, interactable gateway. The gateway is easy to miss if you are riding past it. Interact with the gateway to be teleported to the next section and you will finish the mission.
