Rayque

This comic was expensive to make. I had to sell 1365 Cubic Chaos Blades for this

In-game name of characters in the screenshot: Rayque, Chainey

The recipe for Amaterasu's Helm is one of the more difficult recipes to find, as it is weighted lower than others. It might take several daily runs before you'll find it.

The following Sengoku weapons cannot be obtained by any means:

Amaterasu Bunker Buster (Blaster)*
Amaterasu's Death Bringer (Demon Avenger)
Oyamatsumi's Ancient Bow (Pathfinder)
Susano-o's Energy Chain (Xenon/Pirate)
Tsukuyomi Ritual Fan (Ho Young)*
Tsukuyomi's Energy Chain (Xenon/Thief)

These weapons are all listed in Pet Ignore search, but the recipes do not exist and they do not drop from Mori Ranmaru. You cannot find any of these weapons listed in the Smithing Professions tab, so they cannot be crafted.

MapleWiki's information about Mori Ranmaru's drops and the availability of these items are currently incorrect.

Several bug report topics have been written in the past about the availability for some of these weapons, but to no avail.

The set effects for Critical Rate and Invincibility after hit do not work. It's been reported in the past, forwarded, but no fixes have been implemented.

There isn't much we can do about it. We can only wait and hope for the best at this point.
