trust trustgroup trustall trustnone trustset

Syntax:

trustset <all/group/none>
trustall
trustgroup
trustnone
These commands allow a player to specify how certain questionable spells such as slow and word of recall can be cast upon them by others. If trust is set to "all", then everyone can cast these spells on the player, while if set to "group", group members can cast them freely on the player. If set to "none", then either nobody but the player can cast them on the player, or if they are cast (like slow) then the spell is treated as an offensive attack.
