By employing an animate rock spell, the druid causes a lithic object of a size up to that indicated to move. (See animate object, the Sixth Level cleric spell.) The animated stone object must be separate, i.e. not a piece of a huge boulder or the like. It will follow the desire of the druid casting the spell — attacking, breaking objects, blocking — while the magic lasts. It has no intelligence nor volition of its own, but it follows instructions exactly as spoken. Note that only one set of instructions for one single action (the whole being simply worded and very brief — 12 words or so), can be given to the rock animated. The rock remains animated for 1 melee round per level of experience of the spell caster, and the volume of rock which can be animated is also based on the experience level of the druid — 2 cubic feet of stone per level, ie. 24 cubic feet at the 12th level.
