Start from Windy Peak and run downwards until you reach the Tom NPC where the Mother Bear Quest is, then turn right and jump from the cliff to get to the Waterfall Cave. Walk inside and farm the Hoyuzo Subordinates NPCs - defeating each one gives you a 30% drop rate for one Demon Horn. Go deeper into the cave and grind the Hoyuzo Boss, his drop rate is 50% for three Demon Horns.
If you're on the journey of getting the best breathing styles in Slayers 2, one of the the key components for most are Demon Horns. This guide will walk you through the locations and which NPCs and Bosses to target to get to your goal of becoming stronger. Keep on reading and find out how to do this easy-peasy.
How to Locate the Waterfall Cave in Slayers 2

Before you can get to farming, the first thing you need to know is where to find the Waterfall Cave where the correct NPCs and Boss are hidden. Start your journey at Windy Peak and use the torii gates as your guide. Look where the road takes you downwards, and take that path to descend through the dirt tunnel. Once you reach the new clearing, look for the Tom NPC where the Mother Bear Quest is, and walk right to the edge of the cliff.

This is not where you stop, so just keep going until you fall down because once you land, you'll be right in front of the Waterfall cave entrance. Now all that's left to do is to enter the cave and grind to the max until you get as many Demon Horns as you need.
How to Farm Demon Horns in Slayers 2
To obtain as many Demon Horns as possible in the game, you must face off against the Hoyuzo Subordinates NPCs and the Hoyuzo Boss. As soon as you enter the Waterfall Cave you'll see a bunch of the Hoyuzo Subordinates NPCs, and as soon as they spot you they will try to kill you. This is why it's important to have your preferred build equipped and ready. You also need luck and patience if you want to get a lot of Demon Horns, because this enemy has a 30% drop rate for a measly single item.
When it comes to the Boss Hoyuzo, The Sickle Reaper, you can find him if you go deeper into the Waterfall cave. He is a better target to farm for the item, because there is a 50% chance of three Demon Horns dropping once you kill him. However, this is not an easy thing to achieve if you're a beginner as you need to have strong items, abilities, and overall know what you're doing. This is why we suggest teaming up with fellow players or friends if you find yourself struggling.
