I stumbled upon this topic:

Anndd then I thought, oh so there is a helmet D: He is talking about the Daemon Helmet right? It was quite an old topic so I didn't want to necro it..

But could anyone give me a more exact location of where it is? I've looked everywhere but I couldn't find it ;~;

If you're talking about the Holy Warrior helm, it can be found in the Lost Bay region. It's off the path, just after you've walked the stairs by the house, there should be an off-path to the left - It's in a chest.

Through pain and torture, I shall not falter
With Dragon n' Sword, I'll burn every horde
will fail and Justice prevail...
