Jacobi is an enemy character from Fire Emblem: Genealogy of the Holy War, and is a mercenary serving under the leadership of Chagall. While assembling a battalion to face off against Sigurd's troops, Chagall orders Jacobi to defend Madino Castle, to which Jacobi proudly expresses the utmost confidence, claiming that the Levin Sword will be able to cut down any enemy who gets in his way. When Sigurd's troops arrive at the castle, Jacobi will engage them in battle, and will eventually succumb to their sheer might.

Subjective: The following part of this article is based upon the editor's personal experiences and opinions, and therefore may not be applicable for all readers.
Jacobi is markedly different than the previous castle-guarding bosses the player has encountered. He has a 1-range attack speed of 13, a speed stat only rivalled by a Silenced Sandima. Thanks to his gate and his leadership, his avoid is close to 70. This may cause players who have otherwise had little trouble hitting bosses to suddenly find themselves plagued with miss after miss. Furthermore, his defenses are essentially on par with the armored bosses the player has previously encountered, so a handful of stray hits won't kill him. Jacobi has access to Pursuit as well, so slow units should avoid engaging him unless absolutely necessary.
In order to neutralize Jacobi's natural advantages, the player should attack him with units that have high speed and accuracy. Ayra and Lewyn are natural choices. Utilizing Sigurd's Leadership and Lachesis' Charm can help as well.
As a sidenote, the castle on which Jacobi stands is a bit unusual in that it is surrounded by a pair of choke points. Players attempting to rush the ballista units behind Madino castle might unintentionally send a unit into Jacobi's attacking range, an error that could prove deadly.
Jacobi's Levin Sword is one of the handful of swords that units incapable of wielding swords can acquire. As such, Lex, Finn, and other parents could theoretically obtain the Levin Sword just to pass it on to their children. Doing so is largely a waste, however, as this prevents the player from using the Levin Sword during the first generation, and killing Jacobi with Lex is stupendously hard to begin with. If the player is really so concerned about obtaining the Levin Sword early, it should be handed to Sigurd and then sold to its intended recipient.

Jacobi makes a brief appearance in the Mitsuki Oosawa manga as a mercenary hired by Chagall to liberate Agustria from the occupying Grannvale army. Further context is given to how he came to fight for Chagall, as it is revealed that Chagall had been taxing the remaining villages under his control to pay for Jacobi's mercenaries after hearing of his powerful Levin Sword.
