And here's another point: don't you think that runes are extremely overpowered?
I'd especially like to mention the energy rune and the battle rage rune.
However, compared to other runes, the dragon rune causes much more concern in the mod, as doubling the stats can give a huge bonus. I would call this rune the ultimate one – it will definitely need to be made more expensive (it would be better to remove it if possible).
