Gliders and Grappling Hooks need first to be equipped before they can be used.
Lore, Towers and Obelisks can unlock new locations on the map. This will allow for users to decide on where they want to go next.
Bandages are easy to craft in Personal Crafting but only heal over time. Still useful when running out of health potions mid exploring.
Upgrading the Flame gives bonus stats for all players on the server. Useful boost if they are stuck in an area with enemies that are too strong.
Food gives bonus stats for a short time, for example more health, regeneration in Health or Stamina or Mana, more strength and so on. Depending on how they like to play (mage, warrior, ranger) they should check which food is most beneficial for them and take some with them for exploring.
Plants can also be grown in the base once the Farmer is acquired, which makes it easy to always have a stack of useful food at home.
Upgrade the Flame to unlock the possibility to place more Altars. Place more Altars to have more strategic Fast Travel Points everywhere around the world map (above the Shroud).
Drink Shroud Survival Potions before entering the fog to extend the time you can spent down there.
Take Food with you!
Remember the way you got into the Shroud in case you need to get out of it quickly.
Search for Shroud Time refills in points of interest. They might be there. Use them if needed.
Remember areas with no Shroud. There can be towers that lead up above the Shroud, caves without Shroud in it or ways to areas above the Shroud. Catch some fresh air whenever possible.
Upgrade the Flame Altar or learn the Inner Fires Skill for more time in the Shroud.
Be prepared to fight, enemies in the Shroud can be quite strong.
Take ranged weapons (Bow, Staff) with you, some enemies down there fly and are hard to hit with melee.
