Only the shaft portion of the Spiritbinder can be dyed.
Before the March 23, 2006 update, the Spiritbinder behaved improperly. It did not give the base +10 energy to the wielder, and it fired arrows instead of the expected magical missile.
This item is always customized for the character that the /bonus command was used with. However, this command can be reused on each of your characters, consistently respawning the weapon. Any new mods added to this weapon cannot be salvaged.
Although the weapon is customized for the character, heroes can still use it. When using the /bonus command while a hero has it equipped, it creates a second item in the character's inventory that can be used normally.
This items modifications cannot be salvaged. Any modifications made to the Spiritbinder are permanent until replaced.
