A slender tree trunk is acquired by cutting down young trees, which can be done using a knife or an axe and the Timbercrafting skill.  Each young tree will yield 3-5 slender tree trunks.

A slender tree trunk is used for:

• Constructing traps
• Ceiling and floor sections (4 needed)
• Constructing a shelter (3 needed)
• Crafting Staves
• Crafting Paddles/Sesta
• Crafting Clubs
• Crafting wooden stakes (6-8 stakes made per slender trunk)
