Patch Patch 1.9.64B 2025-04-22
As an Assassin, Yi Sun-shin's playstyle doesn't quite match his intended role. His ability to secure kills in the early-to-mid game has been relatively weak, forcing him to rely on fast resource farming to gain an economic lead and take over the match. We aim to enhance his burst damage potential, and therefore we've completely redesigned his Ultimate. We've also optimized the control experience of all his other skills.

Then he commands the naval fleet to launch 3 waves of cannon shots on the area, dealing Physical Damage and slowing the enemies.

Patch Patch 1.4.86 2020-06-16
One of the main feature of Yi Sun-shin is that he can switch his weapons flexibly according to his distance from the target. However, actually in most of the cases he was playing a ranged role instead of taking advantage of his glaive. Therefore, in this revamp, we have added powerful effects to his each weapon swap, which boosts his melee ability and provides him with more possibilities. As a result, Yi Sun-shin is given another new role: Assassin, apart from his original role Marksman.
The Admiral who can fight using different weapons.

The allied base is transformed into a naval fleet. Every several seconds or after respawn, a Turtle Ship is spawned at the allied base. Yi Sun-shin can board, the Turtle Ship and gains Movement Speed and enhances Traceless.
