The number's right but the list isn't...
He said he'd seen 5
For simplicity let's say they were heraldic 1 through 5
I said 9 left:
3) Gold trim
That leaves Gilded as the only other rune variant and the one I did not include in my numbers.
Edit: After posting this I saw what you meant he put Zammy and Zamorak opposed to Zammy and Zaros or Zamorak and Ancient if we want to be game name correct.
