Hornwood staves cannot be fashioned by PCs without the Carpentry Proficiency (PHB, p. 80) due to the rigidity of the wood. Any character could simply pluck a sapling from the ground and use it as a cudgel, but DMs are suggested to treat these instances as Clubs (PHB, Table 44 – Weapons). This is largely a systematic restriction for game balance.
Hornwood staves are renowned for their strength and durability, and their extra weight gives a +1 to dmg. Non-proficient use of staves are suggested to be viewed as Clubs, not staves.
