Uomo Universale (The Universal Man). The legendary all-roundedness associated with Leonardo da Vinci given shape. It is commonly called an all-purpose, specially-made Noble Phantasm that instantly analyzes the target(s) and adjusts his/her greatest attack in accordance with that (those) target(s) before firing. Apparently, it is originally a reflection-type Noble Phantasm that repels attacks by provisionally composing the enemy’s Noble Phantasm on the spot, but those resources are being utilized for the sake of administrating Chaldea.
In “Fate/Grand Order”, a different shape of da Vinci’s all-roundedness is demonstrated. That is to say, it is a magic attack where his/her gauntlet (an all-purpose gauntlet suitable for every war situation) worn on his/her right hand is modified in the blink of an eye, before it projects pure Magical Energy towards the enemy camp and giving them a “compulsory” fixed damage by means of this attack. This damage is not able to be reduced by any defensive-type Noble Phantasm and Skill, not to mention Anti-Magical Energy abilities————In other words, by putting together a super advanced formula technique that analyzes in real-time, every opponent becomes a susceptible target for his/her Magecraft.
