Demon Horns are a demon-only drop in Project Slayers 2, which means you get them by killing demons rather than buying or crafting them. The fastest concentrated source early on is a hidden cave tucked behind a waterfall in Bamboo Grove, where Hoyuzo Subordinates respawn in a tight loop and the area boss sits at the back.
Quick answer: Drop down the cliff in Bamboo Grove, walk through the waterfall into the hidden cave, and kill Hoyuzo Subordinates. Hoyuzo, the Lv 52 boss inside, drops Demon Horns x3 at 50%.
Demon Horns drop sources in Project Slayers 2
Every enemy that counts as a demon can hand over horns, but the rates and the travel time differ a lot. These are the reliable spots.
| Enemy | Location | Drop |
|---|---|---|
| Hoyuzo Subordinate | Hidden cave, Bamboo Grove | Demon Horns x1 (~30%) |
| Hoyuzo (Lv 52 boss) | Back of the hidden cave | Demon Horns x3 (50%) |
| Blood Hounded Demon | Mistfall Harbor cave | Demon Horns x1 |
| High Demon | Iceveil Valley tundra | Demon Horns x1 (50%) |
Hoyuzo Subordinates are the lowest-level option of the four and the one you can reach in the low 20s, which is why the waterfall cave is the default farm. Blood Hounded Demons hit harder because they use Blood Demon Arts, but the drop rate is better. High Demons in Iceveil Valley have the strongest rate of the regular spawns and the smartest AI, so bring a party.
How to reach the hidden waterfall cave in Bamboo Grove
The NPC Wagwan stands just inside with two quests, “I will clear out his guards (Lv 40)” and “Take care of Heyzou (Lv 50)”. Neither is required for horns to drop, and you can abandon the quest later — for example at Flame Trainer Rengu across Mistfall Harbor, if you would rather start Flame Breathing Training at Lv 25.
Farming Hoyuzo Subordinates inside the cave
The front chamber of the cave holds several Hoyuzo Subordinates that respawn on a short timer, so you can loop the same room instead of running between overworld spawns. They are a step above normal mobs in damage, but a player in the mid-20s with a basic breathing style can clear them one at a time.
Each kill rolls independently for Demon Horns x1, at roughly a 30% chance. Pick the drop up off the ground — it does not go into your bag automatically — and a “Demon Horns” pickup line appears on screen when it registers.
If you die, you respawn at whichever sanctuary crystal you set. Setting Bamboo Grove Sanctuary before you start keeps the walk back to the waterfall under a minute, which matters more to your horns-per-hour than your damage does.
Hoyuzo boss drops (Lv 52)
Follow the corridor deeper past the subordinates and you reach Hoyuzo, the Sickle Reaper, at level 52. One successful kill can pay out more horns than a long minion loop.
| Drop | Chance |
|---|---|
| Exp x100 | — |
| Demon Horns x3 | 50% |
| Hoyuzo’s Haori x1 (Lvl.52) | 12% |
| Muzan’s Blood x1 | 10% |
| Sickles x1 (Lvl.52) | 5% |
| Sickles x1 (Lvl.52) | 5% |
The two Sickles entries are separate rolls, so both can land in the same kill. Muzan’s Blood is the standout side prize here, since it is the item that turns a slayer into a demon.
At level 52 the boss will outclass anyone farming the front of the cave, so treat it as a target you come back to rather than the first thing you attempt. A party makes the fight far more consistent.
Alternate farming spots: Mistfall Harbor and Iceveil Valley
Mistfall Harbor cave
Set your spawn at the Mistfall Harbor crystal in Mistfall Village and ride past the houses to the cave entrance. The Blood Hounded Demons inside use Blood Demon Arts, so they punish standing still, but their horn rate beats the Bamboo Grove subordinates.
Iceveil Valley tundra
Ride into the snowfields past Mother Bear and the Caden boss to find High Demon spawns. They carry a 50% Demon Horns chance, the best of any regular enemy, and they fight with noticeably sharper AI. Several can pull at once, so this is the spot to bring friends to.
Demon Horns in the original Project Slayers
The first game handles horns differently. Every demon kill grants exactly one Demon Horn, and chests that spawn after boss kills such as Kaden and Sabito have a rare chance to contain them. Killing demons directly is still the dependable method.
- Abubu Cave — an underground spot with three demons and a spawn point right at the entrance.
- Zapiwara Cave — Sakurai demons with lower HP and damage, three at a time, and a very close spawn point.
- The woods east of Kiribating Village — heavily populated with demons, with Abubu Cave as the nearest respawn.
Abubu Cave announces itself with a warning prompt at the mouth before you step in. Bring a lantern for Zapiwara Cave — the tunnels are dark enough to lose the demons in.
Horns there also have a fixed use. NPC Tony, who lives in Ushumaru Village beyond Zapiwara Mountain, will not pay Wen for them, but he trades 250 Demon Horns for Claws.
Confirming the horns landed in your inventory
Two things tell you a kill paid out. A “Demon Horns” item appears on the ground where the demon fell, and once you walk over it, an inventory notification names the item and the quantity you picked up. Open your bag and check the stack count if you are farming in a group, since drops are easy to miss in a crowded room.
If nothing drops, the kill simply failed its roll. Neither the subordinates nor the boss are guaranteed to give horns, so the fix is more kills rather than a different route.
