15 N/R here - specializing in Death magic and Blood Magic.
I bought, when I was low level, a square thing (forgot the name) that added 30 armor class and +1 to death magic.
I recently bought 2 "minor runes" which, from what I understand, gets applied to armor to increase the specific statistic thats on it - by a random number from 1-3.
Anyway, I had 8 ranks of death magic naturally. It became 9 when I added the initial crafter made square thing. Then it became 10 when I added the 1st rune - but DIDNT go up when I added the additional rune.
Is there a cap on how much bonus you can get from items? It seems like +2 is the highest combined bonuses I am able to get.

Am I nuts?
