Woodgrues have incredibly sensitive hearing and the innate ability to see in darkness. However, their fairy ancestry means they are vulnerable to pure iron.
Armour must be tailored to woodgrues’ small size. Likewise, woodgrues can only use weapons appropriate to their stature (as determined by the referee). They cannot use longbows or two-handed swords.
Due to their small size, woodgrues gain a +2 AC bonus when attacked by large opponents (greater than humansized).
A woodgrue who witnesses a party, feast, celebration, or festival must partake; they are utterly compelled with every fibre of their being. If, for some reason, a woodgrue wishes to resist this compulsion, they may save versus paralysis (but will feel drained and downtrodden for the length of the engagement).
A woodgrue can see normally in darkness, viewing the world as though it glows in faint moonlight.
Woodgrues have a 3-in-6 chance of hearing noises
As demi-fey, woodgrues suffer 1 extra point of damage when hit with iron weapons (e.g. an iron short sword would inflict 1d6+1 damage on a woodgrue, rather than the standard 1d6).
