Survival

As of December 5, 2022:

Overview
Survival is a special skill in Turtle Wow, you get it from the Nesingwary camp at the north side of Stranglethorn Vale from Rufus Hardwick. You want to get it so you can get Traveler's Tents, which provide rested experience as an Inn does but at a much faster rate such that you can become fully rested in 20 minutes or so. The effect stacks so if you have friends you can set up more tents to have a 'tent party.' As usual, your rested experience is capped at your [current level XP needed to level] x 1.5. You can typically find players set up such tents in Goldshire or Crossroads.

Survival Quest
The survival quest (https://database.turtle-wow.org/?quest=50230) requires picking up: Wood from the Camp, Sturdy Rope from Jaquilina in camp, and Cheap Goblin Oil from Mazk in Booty Bay (found in the Old Port Authority on the bottom floor of Booty Bay.) After you get those and turn it in, you get Survival!

Survival Leveling
Buy 'Unlit Poor Torch' from Rufus Hardwick, which you can convert into 'Dim Torch' with your survival skill. Keep doing this until you get a skill a 50, because it's cheap, only 10 copper per unlit poor torch. Since Dim Torch goes green before you get 50 it will take quite a few.

Once you get 50, you can use the 'Outline: Traveler's Tent' from Rufus Hardwick in the camp. This allows you to create Traveler's Tents. Creating traveler's tents is on a 2 hour cooldown.

(According to the Database, level required is only 5, but you need to get to Booty Bay and be able to not immediately die within the camp. That said, not impossible to do at a low level if the Database is accurate.)
