Note:
Grab normally only applies to a melee opponent of equal or lesser size. Everything else is too big. Because of their
thorny grapple Special Attack, a Child of the Briar can grab two sizes higher, up to Medium, which should let many Pathfinders into consideration!
Children of the briar are a frequent nuisance to fey and mortal alike. They grow in many briar patches but sometimes spawn when a sorcerer or magical creature’s blood is spilled on the forest floor. Despite their size, they gather in great numbers, cultivating the thorny thickets into veritable fortresses. Wise men flee when they hear their clicking language in the underbrush, for the children have a taste for blood and all the capricious wickedness of spiteful children.
From their lairs, the children of the briar creep far and wide to spy on the forest’s inhabitants, sometimes using spiders, monstrous centipedes, and giant dragonflies as mounts. They converse with travelers bearing interesting news, but their words are thorned with gleeful malice, jealous bile, and lies. They are not above murder. They bargain what they learn for trinkets, favors, and drops of spilled blood.
A caster of 3rd level or higher can gain a child of the briar as a familiar using the Improved Familiar feat.
