In other words, the Silver Lynel Saber Horn is the key to making some of the strongest weapons in Tears of the Kingdom. When combined with the right weapons, this attachment can yield a durable 120+ attack power weapon that can be used at any time. While the horn is rare, you can “de-fuse” it at a special vendor right before a weapon breaks and use it again on a different item. Once you acquire one of these, you’ll never be too far from your best late-game weapon.
Savage Lynel Bow
Speaking of Lynels, the most powerful bow in Tears of the Kingdom can actually be acquired by defeating a Lynel. I’m not sure about the guaranteed drop rate, but it seems to be able to drop fairly consistently from any of the Lynel enemies that you defeat.
This bow is capable of firing multiple arrows in a row in a horizontal pattern, which basically makes it a shotgun. Though tricky to use at a distance, it will destroy anything at close ranges. Get one of these as soon as possible, save it for boss fights, and you’ll be set. The Royal Guard’s bow is the best long-rage alternative to this weapon.
There are weapons more powerful than this one, but I’m mentioning it here due to how easy it is to find and its unique properties.
A common weapon among the Gerudo, you’ll be able to find a decent supply of these Scimitars in Gerudo regions. The downside is that they are not very durable. However, they actually gain bonus attack damage from fused items that grant attack power. They’re also incredibly fast. So, if you get a powerful item like the Silver Lynel Saber Horn, fuse it to this, and save the Horn before it breaks, you’ll have a 125+ damage lightning-fast melee weapon. It’s incredibly good.
Finally, I should probably give a shoutout to some of the amiibo weapons in the game. These include items like the White Sword of the Sky, Fierce Diety Sword, and Biggoron’s Sword. Individually, these weapons boast some of the highest attack power in the game. However, they are locked behind amiibos.
