Before heading east to Haunted Bellhart, we recommend getting Thread Storm, a Silk Skill, since its AoE is better compared to the Silkspear. It will be useful against the bosses you will encounter after Moorwing. To access its location, you need to enter the house in Craw Lake first. Inside, go to the top-left corner and then beat the wes of enemies. We recommend using the Reaper Crest for the fight since it is easier to hit flying enemies with it. After beating the enemies, climb up and then hit the mechanism to spawn balloons outside the house.
Head out and then use the balloon to pogo to the skill's location. Finally, bind Thread Storm to Hornet!
