So I was reading the new rune gollem article and it said the red modifiër adds an extra blue rune.
found in the article:
While their reliance on runes may make the Rune Golems seem like a risky choice, their modifier dial allows them to count an additional stable energy when they perform a melee attack or special ability, giving them much needed consistency.
To me its more a boost on your defense. Like boost the defense by this many blue runes. Is this a mistake I might be overlooking it in the rules I cant find it at the moment.
