This is my first mod.
I made this because I really wanted to use Carsomyr from Baldur's Gate 2. This weapon is based on Tyr's Justice at Baldur's Gate 3 Nexus - Mods and Community (nexusmods) from https://www.nexusmods.com/baldursgate3/users/21928689.
I also used https://www.nexusmods.com/baldursgate3/mods/249 Mod from https://www.nexusmods.com/baldursgate3/users/100288838.
Also inspired by https://www.nexusmods.com/baldursgate3/users/7296843. https://www.nexusmods.com/baldursgate3/mods/1660 Salune
armor set. First of all, I would like to thank these people. Also, this weapon is OP enough on its own (lol), but it becomes even more OP when combined with the Salune Armor Set from https://www.nexusmods.com/baldursgate3/users/7296843 (lol).
Furthermore, I would like to thank everyone on Japan's "5 Channel" who taught me a lot of things even though I knew nothing about programming.
I intended to make swords that could only be equipped by non-evil paladins, but I didn't have the technology to make that happen, so I decided to make many swords only usable by Oathkeepers (paladins excluding Oathbreakers). . ability. This sword can be wielded by any class, including Oathbreakers, but only three types of paladins can take full advantage of Carthomil's abilities: Oath of Devotion, Oath of the Ancients, and Oath of the Ancients.
I tried to bring the performance closer to BG2's Carsomyl, but since the magic called dispel magic doesn't exist in this game at the moment, I omitted it and made it possible to use Ancient Paladin Aura, which halves magic damage (I want to use Ancient Paladin) I'm sorry if I diminished that feeling).
I'm not good at English, and I used Google Translate to write this text and the explanations inside the weapons, so please forgive me if some parts of the English explanations, such as the explanations of weapons, are unnatural.
This time, I made a sword exclusively for Oath Keeper, but if I have time, next time I'm thinking of making a special weapon (Ir'revrykal/unholy reaver) for Oath Breaker that appears in BG2 (I can make it myself lol)
Carsomil can be obtained from the first tutorial chest or dropped by defeating Adamantine's golem. If you have already given these, you can get them from Spawn any Items or something similar.
