It doubles the color advantage/disadvantage from 20% to 40%. This applies offensively and defensively. So a blue tome will deal 40% less damage to someone with an emerald axe while a red tome would deal 40% more damage. Like 0 Dislike 0 Log in to post comments Report
To expand on this answer, the effective attack of both parties will be 40% higher/lower before comparing with defenses, so it's not like your final damage will be 40% more or less. Like 0 Dislike 0 Log in to post comments Report
