For him to be damaged, he must be hit by A-rank attacks or above, requiring the opponent to have at least an A-rank "
normal attack" registered through their Strength
statistic, A-rank
magecraft, or an A-rank Noble Phantasm. It only works based on rank and not numeral equivalents due to its "
refusal" property that "
goes beyond the rules of reality", meaning that, although a C-rank Noble Phantasm can be considered A or A+ rank in terms of a regular attack, it would still be nullified by God Hand. Even should an attack be capable of destroying the world,
Saber believes it would be nullified should the rank be too low.
