Oaken Guardian

This magic item is a large oak tree that can transform into a treant (see the Monster Manual). The creator of an oaken guardian gives it an 11-word trigger phrase that tells the treant what to do and when.

You must create the oaken guardian within 300 feet of something it is meant to protect. A druid can create multiple oaken guardians if she likes, but they must each be near something that needs protecting.

The oaken guardian returns to its treelike state when it has accomplished its objective. If it is killed, it is no more. However, if it is only damaged, it can heal normally—as a treant would, not a tree—even in its treelike state.
