Rune Breaker (Japanese: 破邪封呪, Romaji: rūn bureikā) is a defensive white magic technique.[1][2]. Strictly speaking, it is not really a spell, but the name of a magic circle that affects all spells cast within it.
By creating a ward in the shape of a pentagram, all black and shamanistic spells are weakened within, while if the ward has the shape of an hexagram, white magic spells are strengthened, while the aforementioned two types of spells remain suppressed. (It was never demonstrated in-universe how a Rune Breaker would affect a spell belonging to holy magic.)
The strength of the ward does not depend on the skill of the caster, but instead on the size of the ward itself. The larger the ward, the weaker spells and other supernatural abilities become. Interestingly, if the ward is not strong enough to affect all spells, it affects the stronger ones first, while weaker magic remains unfazed. A sufficiently large ward would completely nullify spells cast within.
Saillune City is for all intents and purposes a Rune Breaker ward, as the entire city is arranged in the shape of an enormous hexagram. Even then, it's not big enough to completely nullify any spell.
