To get Sun Breathing in Weak Legacy 2, you need to do the following:
- Reach at least Level 50 in the game.
- Obtain 100,000 Yen.
- Get the Sun Soul item, which is required and must be equipped from your inventory.
- Go to Yoriichi, who is located on top of a mountain/hill right outside of the spawn Starting Village. Climb past Kokushibo to reach Yoriichi.
- Talk to Yoriichi with the Sun Soul equipped and the required level and Yen to buy Sun Breathing V1.
To get the Sun Soul, you need to defeat Tanjiro in the Boss Raid at Slayer HQ village, which is to the left of the Starting Village. The raid is best done around Level 50 or higher. For Sun Breathing V2, you need to:
- Unlock all Sun Breathing V1 moves.
- Be part of the Kamado Clan.
- Speak to Yoriichi again and succeed in a raid he teleports you to.
This makes Sun Breathing one of the most powerful movesets in the game but it requires significant effort and resources to obtain.
