Blackwyrm Coat

The Blackwyrm Coat (ブラックウィルム・コート) is a player-made black leather coat that Kirito wears in the final months of Sword Art Online.

Background
The coat is actually Kirito's 4th leather coat in the game, as he does have to occasionally upgrade his equipment. It was tailored from black dragon leather, a high grade raw material, by Aincrad's best player seamstress, Ashley.

Abilities
The coat provides the user with a high hiding bonus, allowing the user to hide from monsters or players that lack a high Searching skill.

Trivia

 * Kirito tends to wear this favourite coat of his even in the middle of summer, saying that he has become so used to it that he cannot calm down without having it on.
 * The Blackwyrm Coat was among the items that Kirito inherited in ALfheim Online from his Sword Art Online save data, due to the two games having an identical save format. However, as all the items were corrupt and could have been detected by the system's error detection protocol, Kirito deleted all of the items.
 * Light Novel illustrations depict Kirito wearing a coat identical to Blackwyrm, as early as February 2024. If it is the same coat, then this means that the Blackwyrm Coat was in use for the better part of a year, meaning his other 3 coats were used for a relatively short amount of time. However, it is also likely that Ashley tailored multiple coats that look alike, for Kirito.
