The script makes totally no sense for me too... i see only client side thingies...
So, your option for casting the seal of ruler w/o being near the artifact (server side), but being near it (client side) is kinda wrong...
If you are at blazing swamp , going for aden for example, and use that script, you will be teleported to the artifact, but IN CLIENT ONLY, meaning that you are still in blazing swamp on server side... and even IF YOU CAN target the artifact, there is some range of seal of the ruler, so you wont be able to cast it cuz u are too far away(server side)
The only way you will be able to cast it, is when the server dont have geodata at all, you just need to go near the artifact (outside, aden's back), use the script, get near the artifact, try to cast the seal, and ur server side char will start walking towards your client side char, walking trough walls cuz no geodata...
Thats my thoughts of that script...
