I Rely on Monster Fragments to Become an Adventurer

[Pseudo-DND] [Hodgepodge World View] [Adventure] [Rogue] Ian, who traveled to a fantasy world, originally wanted to be a scribe in a monastery and live a stable life with an ordinary wife. However, he was expelled just three days after traveling and was forced to join the dangerous adventurer ranks.​ Fortunately, he has a golden finger "monster fragment system". By collecting enough fragments of the corresponding monster, he can not only transform into the monster, but also inherit its abilities completely!​ In the goblin lair underground in the forest, Ian has transformed into a giant goblin: holding a mace in his hand, covered in armor, and his body is far larger than that of ordinary goblins. Stare at the three major skills of [Stealth], [Dark Vision] and [Reproduction] on the panel. He activated his ability on the spot, smashed the goblins to death with one blow, and roared, "Come to greet your king! Give your life!" A bloody battle ended, 100 Goblin fragments were accounted for, and only the corpses of Goblins were left. Looking at the fragments on the panel that were enough for another transformation, Ian turned around and put all the fragments into the [Stealth] skill - [Stealth LV.4 → LV.5] From then on, using the fragments as the cornerstone and transformation as the sharp edge, Ian started his adventure.
