If it's difficult to write it yourself, write here everything you need, down to the specifics, and I'll write the script.
No need for specific details... Here's what I need: There's a Trigger(OBJECT_TOUCH_TRIGGER, ...). I need something to happen (e.g., a message is displayed) 2 weeks after this trigger is activated.
And another question: can I place the Tear of Ashi on the map as an artifact? I mean, not buried, but like all the other artifacts.
