You can Plant the haft end of the rod in the ground, whereupon the rod's head sheds
Bright Light in a 60-foot radius and
Dim Light for an additional 60 feet. While in that
Bright Light, you and any creature that is friendly to you gain a +1 bonus to
AC and
Contesting Rolls and can sense the location of any
Invisible hostile creature that is also in the
Bright Light.
The rod's head stops glowing and the effect ends after 10 minutes, or when a creature uses an action to pull the rod from the ground. This property can't be used again until the next dawn.
