Talk:Magus Vigor/@comment-97.33.192.130-20180223181636

I have been trying to get the magus vigor arcane and I notice it needs three radian sentirum. I went to that site and it says that it requires ten instances of the three, which means it needs 30 radian sentirum to fully level it up. I went back to the magus vigor page and it says there are only four ranks of leveling up. Did I read something wrong or are the two sites contradictory or what? How many radian sentirums do I need?
