Spells (3e)

Waves of energy roll forth from the character, moving in the direction that the character determines, causing all wooden objects in the path of the spell to be pushed away from the character to the limit of the range. Wooden objects larger than 3 inches in diameter that are fixed firmly are not affected, but loose objects (barrels, siege towers, etc.) are. Objects 3 inches in diameter or smaller that are fixed in place splinter and break, and the pieces move with the wave of energy. Objects affected by the spell are repelled at the rate of 40 feet per round.

Objects such as wooden shields, spears, wooden weapon shafts and hafts, and arrows and bolts are pushed back, dragging those carrying them with them. (A creature being dragged by an item it is carrying can let go. A creature being dragged by a shield can unlimber it as a move-equivalent action.) If a spear is planted (set) to prevent this forced movement, it splinters. Even magic items with wooden sections are repelled, although an antimagic field blocks the effects.

The waves of energy continue to sweep down the set path for the spell’s duration. After casting the spell, the path is set, and the character can then do other things or go elsewhere without affecting the spell’s power.
