- Unlocking Weavenests: Known gate locations include Moss Grotto (Bone Bottom) and the Far Fields. These gates lead to secret rooms called Weavenest Atla and Weavenest Cindril, respectively.
- Finding Upgrades: Inside Weavenest Atla, it is said that a strange figure resides who can enhance Hornet’s abilities. Finding this room is a top priority for any player.
- Special NPC Interactions: Playing the Needolin near certain characters may trigger unique dialogue or even start hidden quests. Experiment often!
Combat Tactics

- The Perfect Combo (Needolin + Needle Strike): Stun a powerful enemy with the Needolin, then take your time to fully charge a Needle Strike for massive, unhindered damage.
- Set Up for Silk Skills: Immobilize a group of enemies and then unleash an area-of-effect Silk Skill like Thread Storm to hit all of them without any risk.
