Willowshore Curse: Research Points

According to Auntie Wu's sheet (adding the +⭐⭐⭐ above), we currently have 9 Research Points?

2 Research Points
The curse borders to the north, south, and east are subtle and hard to interact with without stepping directly through them, whereas to the west, the Wall of Ghosts is a visible barrier with recognizable spiritual elements—as such, it’s likely an easier barrier to attempt to remove. Further, the ruins of the Tan Sugi monastery lie beyond this wall, and if this site can still be reached, the lore and libraries within will be invaluable in learning more about the curse itself. Construction on the Tan Sugi monastery began back in 7020, the same year Willowshore was founded, but the monastery was abandoned in 7062, and much of its lore was lost or forgotten.

The noppera-bo who dwelt in the abandoned lumber camp seemed to believe a “paradise” awaited them beyond the Wall of Ghosts, but perhaps the truth is something else entirely? Others among them worshipped something named “Kugaptee”—a name that sounds familiar but that likely requires more research to learn more about.

6 Research Points
The name Kugaptee is associated in certain old texts with the Tan Sugi monastery and was the name of a powerful nindoru fiend defeated hundreds of years ago by a hero named Tan Sui-Jing. The old legend says Tan Sui-Jing also perished in the battle and that she reincarnated into the towering sugi tree that served as the focal point of the Tan Sugi monastery. Perhaps more information about Kugaptee—including the possibility that the curse might be associated with the fiend—still resides within the abandoned monastery walls?

The above info is not new, something the party has already learned (keeping everything here together so as to support your understanding of these developing plot points in PbP medium).
Yami's little experiments lead Vekka to surmise the new info below - and to fully understand the scope of the Research (10 points taps us out)

Before the Tan Sugi monastery was abandoned, the monks performed daily rituals to ensure the health of the sugi trees, but now that the place has been left to fall into ruin, the most likely source of the curse seems to be Kugaptee’s influence seeping out into the region— particularly given the fact that the monastery appears to be hidden inside a cursed shroud of its own. By spending a little more time researching and drawing upon methods the noppera-bo were attempting to utilize in the previous adventure, the PCs could develop a specialized ritual that might allow passage through the Wall of Ghosts.

10+ Research Points
(This is the final threshold... and allows the party to develop for immediate use the "Open the Wall of Ghosts" ritual!)
