a simple solution would be give it a dur of 0 would only last so long other then that
you could prob make a npc that checks time and checks what items are equip
example
[@main]
#if dayofweek sun then | dayofweek could be used with sun mon tue ect...
#ACT
checkitem PearlRing |Check if its in your bag
#ACT
checkitemw PearlRing 2 |checks for items equiped the 2 is to look for 2 rings
#ACT
takecheckitem |Takes all items that were checked
#Say
Sorry I need these back \\
this should work
but the only problem is it would only check for the item when you click the npc
the only way i could think that it could work is if you use a quest command and i haven't read into that yet
anyway I hope this helps some
