Gáe Dearg: Crimson Rose of Exorcism (破魔の紅薔薇, Hama no Benibar?) is a two meter long spear that renders magical enhancements and projections useless by severing all ties with prana. It was passed down to Diarmuid Ua Duibhne from his father, and he normally keeps it wrapped in a talisman cloth to seal its abilities and keep it from revealing his identity. Unlike most other Noble Phantasms, the abilities of the spear are passive in nature. It does not require its name to be called upon in order to be utilized, allowing it to instantly affect whatever it strikes.
The spear will pierce directly through any projection made of prana, such as Saber's summoned armor, bounded fields, such as Invisible Air, will have small fissures created that slowly chip away at them with each strike, any weapon that is magically enhanced, such as those enhanced by Knight of Honor, will have its enhancements and ability boosts rendered useless when struck by the spear, and any item that acts as a prana source, such as Prelati's Spellbook, will have all connections severed to its recipients.
The nullification is not strong enough to cancel or break the source of the magecraft, making it unable to sever completed magecraft such as contracts exchanged in the past or curses in the way that Rule Breaker completely nullifies them. The effects only last while the tip of Gae Dearg is in contact with the object, which allows it to function as normal after the spear is lifted away. While it is not a weapon one can pride on its destructive power, it can be considered a threatening "anti-Noble Phantasm" and "Noble Phantasm killer" to those that find pride in the power of the armaments, forcing them to defend only by physical means.
