I'm sure we've all been there. That at least one monster that has you trying everything but you can't win. For me there were quite a few. In GU, it was Great Maccao, don't judge me. In base Rise, it was Magnamalo, I absolutely hated it at first and almost gave up. And now in Sunbreak, it's Gaismagorm. I got crushed by it recently and now it's more of a wall than any monster. I'm still hesitating to hunt Glavenus in GU. But if I can't break this wall, I could always go back to GU for a while.
