nowai... why would errende be 10m?
it COULD be useful, but chances are so low you're probably better off potting in most cases. In some cases you really do need it to proc, but it's just 5%...
1-4m at most imho...
i saw that +3 int for 100m too, but personally i don't think INT is a desired stat for diab robes. Tho if you do need it, i reckon 100m is a bargain (just comparing to average chances)
