What is the Needolin?
The Needolin is a “Holy Weaver talent” that allows Hornet to play ancient melodies by stringing Silk along her needle. In gameplay terms, it is a key that unlocks specific doors and likely has combat or puzzle-solving applications.
- Function: Its primary use is to open large, ornate doors marked with a distinctive spider mask symbol.
- Resource: Using it expends Silk, which can be replenished by striking enemies.
Step-by-Step: How to Get the Needolin
1. Defeat the Widow Boss
- Boss Location: The Widow is located in the Bellhart area. To reach Bellhart, you must first obtain the Cling Grip (wall jump) ability in Shellwood.
- The Fight: Defeat the Widow in combat. This is a significant boss fight that will test your skills.

2. Claim Your Reward
Upon defeating the Widow, the Needolin will be automatically added to your inventory as an Ancestral Art. You do not need to find it in a separate room; it is the direct reward for victory.

How to Use the Needolin
Using the Needolin is simple but crucial for progression.
- Find a Spider-Mask Door: These are large, imposing doors with a circular emblem that looks like a spider’s face. They block critical paths, especially in areas like Greymoor.
- Approach and Hold the Button: Stand in front of the door.
- On Controller: Hold the button you have it assigned to (e.g., Y or Triangle).
- On Keyboard: Hold the designated key (e.g., C).
- Watch the Animation: Hornet will perform an animation, playing a melody and using Silk to unlock the door.
- Proceed: Once the animation is complete, the door will open, allowing you to continue your journey into new areas like the upper sections of Greymoor.

Why You Need the Needolin
