Destroyed items
From AmtWiki
Destroyed: Items that are destroyed may be repaired using the Mend spell or appropriate class ability unless otherwise noted under the description of the effect which destroyed the item (example:Warp Wood). A destroyed weapon or shield may be recovered by returning to base and waiting for a 100 count. This simulates retrieving a new one from base. Destroyed items may not be used until they are repaired. Destroyed armor may be repaired by using the Mend spell for each point in each location to be recovered.
