Embedded Shard
Shards embedded in Leaf and Arbor's bodies. There are lingering traces of Dark Arts. It might be the reason why Leaf and Arbor have been unintelligible. Gather and take them to Researcher Pio.
Not dropped by monsters.
Cannot be spoiled.
The chances are official (x1). On servers with x10, x100 and higher rates, drop and spoil come more often.
