BLG moved one step closer to victory, reaching match point with a win in the third game. Much like in Game 2, 'Kanavi' Seo Jin-hyeok was heavily suppressed, and the repercussions of that early deficit persisted throughout the match, ultimately securing the win for BLG.

In Game 3, BLG surged ahead from the start. 'Xun's' Nocturne kicked things off by catching 'Kanavi' Seo Jin-hyeok's Xin Zhao in the jungle, then followed up with consecutive ganks in the top lane, handing 'Zeus' Choi Woo-je's Olaf two early deaths. To make matters worse for Hanwha Life, they lost a dragon they had nearly secured and conceded a kill to 'Viper' Park Do-hyeon's Varus. A desperate bottom-lane dive resulted in only a 2-for-2 trade. Less than 10 minutes in, every metric favored BLG.

Pushed onto the back foot, Hanwha Life attempted to claw their way back. A bottom-lane gank by Xin Zhao allowed them to pick off 'On's' Alistar, and they traded the second dragon for a kill on Varus. In a top-lane skirmish that nearly turned into a disaster, 'Gumayusi' Lee Min-hyung's Xayah—who had grown strong with four kills—survived to pick up additional kills. However, 'Zeka' Kim Geon-woo's Ryze was caught out, forcing them to concede the third dragon. A teamfight attempt using Ryze's ultimate skill during a standoff only led to another death for Olaf.

Around the 27-minute mark, the Ocean Soul appeared for BLG. Hanwha Life, needing to contest, initiated the dragon, but BLG's 'Xun' stole it and took down Xin Zhao. After a chase, they also caught 'Delight' Yoo Hwan-joong's Rakan and secured Baron. Empowered by the Baron Buff, BLG pressured the mid and bottom lanes simultaneously. They picked off Olaf in the side lane and destroyed both the top and mid inhibitors. Shutting down Hanwha Life's final resistance, BLG clinched the victory in Game 3.
