Runes based on game difficulty

[Zechnophobe]

Runes are Constant. Are you playing a different class this time? Not all skill trees use the same amount of runes. That is, you need far more Might runes to get Magic skills, than you need Magic runes to get Might skills. This can sometimes make it feel like you aren't getting as many runes, but in actuality you just spend ALL of them on Magic skills.
