When a hero receives both a superboon and a superbane, the resulting change will be ±4. Likewise, when a unit has a superbane (lowered IV) in a weak stat, the value will be 4 points lower than the base stat. When a unit has this strong stat (called a superboon) as its IV, it will result in +4 points to the base value.
5★ heroes can have stats that are strong or weak (these are not present for 4★ heroes and lower).
