About four years ago I ran across a tabletop system I really liked, but neglected to save the file. It had a magic system rather like Ars Magica's - you picked a form and an element and paid a cost to cast them.
The reason I know it's not Ars Magica is that "Creo Temporis/Create Time" was possible: there was a very memorable example of making a "solid time" sword. I'm pretty sure Space was also a valid element.
There was something like a breakdown of each element into levels - you'd add some number (to the difficulty? to the level requirements?) in order to get more complex effects. I'm fairly sure this isn't Mage, because I remember an 8 showing up in those numbers and WoD only ever goes up to ten in rare occasions. I'm afraid I don't remember the dice used, though I'm fairly sure it wasn't d10.
Does this sound familiar to anybody?
