[Event] [Weekly] Gorgo's Nightmare (Hard)

Rahim in the Basilisk Den is in pain as he is going through petrification. Recently he's heard that Gorgo's Nightmare Fragments can delay the petrification process, so go defeat <Possessed by Darkness> Basilisk Guardian and collect Gorgo's Nightmare Fragment x4 to bring to Rahim.

※ You can exchange Gold Bar 10G x1 for Gorgo's Nightmare Summon Scroll from Tarek Yanzi NPC Knowledge, the node manager of Rock Post, to summon Basilisk Guardians.
※ This quest requires you to defeat Basilisk Guardians, then loot Gorgo's Nightmare Fragments x4 and hand them over to Rahim.
※ This is a weekly quest that resets at midnight (midnight (server time)) 7 days after the day of its completion.
