Liveoak

This spell enables the druid to select a healthy oak tree and cast a dweomer upon it so as to cause it to serve as a protector.

 The spell can be cast on but a single tree at a time, and while a liveoak cast by a particular druid is in effect, he or she cannot cast another such spell. The tree upon which the dweomer is cast must be within 10 feet of the druid's dwelling place, within a place sacred to the druid, or within 10" of something which the druid wishes to guard or protect. The liveoak spell can be cast upon a healthy tree of small, medium, or large size according to desire and availability. 

A "triggering" phrase of up to a maximum of one word per level of the spell caster is then placed upon the dweomered oak; for instance, "Attack any persons who come near without first saying 'sacred mistletoe'" is an 11-word trigger phrase that could be used by a druid of 11th or higher level casting the spell. 

The liveoak triggers the tree into becoming a treant of appropriate size and attack capability, matching the specifications of the Monster Manual de-scription, but with only a 3" movement rate. 

An oak enchanted by this spell will radiate a magic aura, and can be returned to normal by a successful casting of dispel magic or upon the desire of the druid who enchanted it. 

The druid needs mistletoe to cast this spell.
