Questmaster: Lady Undya [The Towne of Xaventry]
This quest is called 'Evoking the Earth', for Adventurers levels 20 to 250.
Description of Evoking the Earth:
Since you don't seem to be the DRUID you could be, I have a lesson for
you. As a DRUID you have the power of nature at your command. Go and
see the druid instructor in the Dira Schoolhouse to learn about how to
EVOKE the EARTH itself against your enemies. This evocation will
cause the plant life to restrain your opponents, forcing them to stay in the
same area as you, and making them considerably more vulnerable. You might
need additional training, so visit Sorina in Lowangen, and a high priest of
earth in Sigil. While in Sigil, visit Lord Vendredi and see if he has any
need of your services. Keep your eyes open for an opportunity to use this
evocation.

+++This quest requires you to use the skill Earth Evocation to
complete a special phase. If you do not have access to this spell at this
time, you can turn in the incomplete quest at no penalty.
Upon successful completion of this quest you can receive up
to 45 quest points, 4 practice points, 50000 experience points, and 3500 gold pieces.
