Rammuha is the first big boss you'll face in Flintlock: The Siege of Dawn. She has three arms, she's weird with them, and she has a ton of moves to learn. Here I'll walk you through the fight with my Rammuha boss guide.
How to defeat Rammuha in Flintlock: The Siege of Dawn
Once you reach the Kneeling Keep and enter the Chamber of the Judges, Rammuha will come down and start babbling about Gods of death or something. The intro cutscene tells you everything you need to know about this boss; she has three arms and she is more than ready to use them.
Two absolutely crucial skills for this fight are Counter Shot and Poised Shot. Counter Shot allows you to perform a gun attack after a parry instead of just a melee attack, and Poised Shot (which requires you to unlock Counter Shot before you can even perform it) is without a doubt one of the best skills offered in the entire game, as it allows you to parry unblockable gun attacks.
Rammuha has a lot of unblockable attacks. If you can not only counter these attacks but also punish them, you're already on your way to making this fight a lot easier.
