As they roam around the countryside, wreaking havoc on everyone they
encounter, reavers draw the attention of the powers of destruction. If they
are fed enough destructive energy released from broken items and slain
creatures, these powers may grant boons to the reaver. The most common boon is
this spell, which increases the reaver's overall combat performance for a
short time.
Syntax: cast glory of destruction at amount <percent>
The <percent> is 1% to 100% of the maximum power you can call upon.
