Well ik the brush is an item from the plugin but I think it is removed. Also those levels can not be reached (Engineer&Architect) so this does not really matter. If U are able to reach them then I am stupid and u can just ignore me.
The required wand levels to upgrade those spells are turned off as they would allow you to be able to basically have world edit. As we do not allow non-staff to have access to world edit on any server other than Creative we cannot allow you to have access to those wand levels. As such we do not have them enabled for anyone to have access to use.
