Selecting spell schools will show the tool's Adjusted Scaling when casting those spells. This can help find casting tools that unexpectedly outperform more common choices when paired with your build's spell choices.
* Note: The "Estimated" Scaling values are not a perfect reflection of how damage is affected. Schools' bonuses are applied AFTER defense (a nonlinear reduction in damage), meaning the "Estimated" values will be less accurate when casting spells with low AR against targets with high defense for that damage type.
