How to Collect Monster Weapons and Wearables
Weapon Drops
Several monsters carry signature weapons. Defeat the monster to obtain its weapon: Babyface's Axe from Babyface (The Hills Run Red), Candy Man's Hook from Candy Man, Chucky's Knife from Chucky, Freddy Krueger's Glove from Freddy Krueger, Ghostface's Knife from Ghostface, Jason Voorhees's Machete from Jason Voorhees, Leatherface's Chainsaw from Leatherface, Michael Myers' Knife from Michael Myers, Pyramid Head's Sword from Pyramid Head, and Victor Crowley's Axe from Victor Crowley.
Wearables
Three monsters drop wearable gear. Captain Spaulding drops Captain Spaulding Hat. Pinhead drops Pinhead Helmet. Pyramid Head drops Pyramid Head Helmet. Equip these in the helmet slot to wear them.
Other Items
Bullet and Smith & Wesson Model 15 form a ranged set — hold the Smith & Wesson Model 15 and use Bullet as ammunition. Pennywise Hair is tied to Pennywise and Pennywise (1990).
Strategy
Spawn the target with its Spawn Egg in a controlled arena. Fight it in open ground so its weapon swings do not corner you. After the kill, pick up the drop before it despawns. Store weapons in a chest near your arena so repeated fights build a full collection.
