Warp Wood (Sp): A wood woad can use a warp wood effect, as the spell, at will. Attended objects can avoid the effect with a DC 13 Will save (but if a saving throw succeeds, the wood woad can simply produce the effect again in the following round). Caster level 8th. The save DC is Wisdom-based.

Treewalk (Su): At will, a wood woad can enter a living tree as a free action and exit from it or another living tree within 60 feet, continuing as though the distance between the trees had nor been crossed. A wood woad moving in this manner can charge or run through trees so long as it moves in a straight line.

The entrance and exit trees must have girths at least equal to the wood woad's, and the wood woad cannot take nonvegetable items or other creatures with it when it treewalks. A wood woad can exit a tree on any direction and from any part of the tree that has enough girth.

A wood woad can remain inside a living tree for as long as it wishes. A wood woad inside a tree senses the world around it normally and automatically knows which trees within 60 feet are living and can accept its girth. If the tree in which a wood woad hides is chopped down, burned up, or otherwise killed, the wood woad inside dies.

This ability is a teleportation effect.

Skills: Wood woads have a +4 racial bonus on Balance checks and Hide checks. A wood woad has a +8 racial bonus on Climb checks and can always choose to take 10 on Climb checks, even if rushed or threatened. *In wooded areas, a wood woad gains an additional +4 bonus on Hide checks.

Wood woads attack any creature not native to their forests. They charge foes from some distance away, using their treewalk ability to cross the distance swiftly. After they warp their foes' wooden weapons and strike a few blows, wood woads flee and watch to see if their enemies go away.
