Cursed Weapons

How To Obtain a “Cursed” Weapon:
Each weapon requires one type of “Ancient Dragon Tribe Blessed Stone”, two types of fossil materials, and “Nightmare Stone”.

First you must obtain a pickaxe/mattock from [Hepa’s Disciple] Shozin in Moradon:

The pickaxe costs 100 Nation Points and 1,000,000 Noah. After purchasing the pickaxe it will appear as a weapon called [Mattock] in your inventory. All the materials for the Cursed Weapon can now be obtained in Ronark Land. Using [Mattock], you may now harvest the Draki fossils found in the Northeast and Southwest regions of Ronark Land:

After finding the fossils. Equip [Mattock]. The Pickax [Mattock] cannot do damage to anything/one except the fossil and nothing can do damage to the fossil except the [Mattock]. The fossils do not attack and when “killed” will drop 1-2 random materials:

All the different “Ancient Dragon Tribe’s Blessed Stones” can be obtained from the four different bosses that appear in the northwest and southeast parts of Ronark Land: Enigma, Cruel, Hell Fire, and Havoc. A different Dragon Tribe Stone is needed for each weapon (the exact recipes can be found by asking [Hepa Pupil] Shozin)

The subordinates of these bosses (Medicmash, Nigmash, and Keramash) which appear around the boss also have a small chance of dropping one of the Dragon Tribe Stones or one of the fossil materials.
The path to get the last material, the “Nightmare Stone”, starts with the 7 sins bosses. The 7 sins bosses appear outside the bowl in Ronark Land as well as sometimes from chests in Krowaz.
Now with all the materials, you can return to [Hepa Pupil] Shozin and select “Manufacturing”. You can then put in all the materials for the weapon and hit “Compounding”.

If you do not remember the materials needed you can hit “Formula” )or “Check Manufacturing recipe” from the first list) and the Pathos Book will open with all the various recipes for you to check.
