M2 Hunter Seeker

Strategy and Synergy
The fire-and-forget nature of Hunter Seeker means that the player can keep spamming the fire button while shifting the focus towards dodging the enemy attack. It's really effective against all but the most mobile of targets, such as Selicy (Boss) and Shiso (Boss), who often can dodge the projectiles during their respective boss fights.

As a weapon, greatly increases the damage output in the long run.
