Q: What changed with Levitate on the last patch?

A: Levitate was changed so that if you already have the Levitate spell on your
character, no other levitate effect will take hold. This was done to
prevent a certain
abuses of the spell which involved chain casting levitate to reach areas
which were not
designed to be player accessible.

To get your levitation spell renewed, you can click to dispel it (this is
one of the
few spells that everybody can click to remove). Once the spell has been
removed, you will
be able to have it renewed.

Bards were unintentionally hurt with these changes - their song will not
overwrite its
own levitate effect. This error will be fixed with the next patch.
