This one has me stumped. Any advice for weapons on how to beat this one??

I use for my primary weapons Tempestuous Bladed Gauntlet and Shinwas Lightning. It's one of those "get in and kill it fast before it kills you" opponents.

You will want to try blocking water, wind and light. I probably used Manifesting Weapon and Swashbuckle. I probably modded the weapons with some sort of light defense crystals and maybe some attack water crystals as well. My memory is fuzzy, because I battled straight away and got it over with! It was not a pleasant experience. As suggested, if you have Tempestuous Bladed Gauntlet, that will block some water and light. Alpponz doesn't block water or magma.

If you have Sword of the Seven Seas, then that's the ideal weapon to use. I don't own that weapon and was still able to get 10 wins (it was tough though). Knowing me, I used a Dark Water Potion each turn to increase damage a bit. Ocean Currents Scroll is good, as it does some water damage and blocks some water. Sancturia Exodin Scrolls will block some light and wind too.

Thanks. I do have MW & Swash, but not the other two. I'll switch my mods up and see what other higher tier weapons I have that will hopefully work. Thanks for the advice.

You're welcome! You may want to equip Phoenix Quill and Reviver of the Lion if you have it. A Spacial Abyss scroll or two might be good for when you need to use your healer. Or you can pair your healer with a total blocker like Shinwas Temple Shard. Good luck!

I have those two and they permanently in my arsenal. Lol.

I hear you! Ha! If you need to borrow any scrolls or a total blocker (Shinwas Temple Shard, Rainbow Vortex), just let me know! I have Ocean Currents, a couple of Spacial Abyss, some Sancturia Exodin and The Void scrolls that may help.
