rune

I thought major and better runes took away health, but i found a major rune of absorbtion with no modifier

can anyon ehlpe? do certain runes have - on them? do certian runes not take away hp? or is it random

I've gotten a Major Absorption that had no negative modifiers, and then a Major Strength that had a -50 modifier. I've no idea if that's random, or actually consistent across all runes of the same type. Just check the specs before buying or applying... if it says "-xx to whatever" then it has a negative modifier.

Absorption does not have a negative modifier.
Runes that modify your attributes will have the -mod
