One of Link's most consistent weapons is the Bow, and Tears of the Kingdom gives you one very early on. Having ranged attacks is a necessity for surviving in the game, so it's smart to pick up Arrows whenever you can.
Even smarter is to pick up as many materials as possible such as plants and minerals, so you have more things to Fuse to your Arrows. This allows you to make them even more effective in battle or even turn them into useful tools. On that note, there are certain items that have the best results when you use Fuse them to Arrows.
8 Bomb Flowers
The classics are classics for a reason… because they're awesome. Now while Link has access to his usual bomb disposal methods, Bomb Flowers are in full in Hyrule. You can find these flowers growing near rocky formations and sometimes in caves.
By Fusing them into Arrows, the Bomb Arrow makes a triumphant return. It's the perfect weapon for ambushing a group of enemies or dealing heavy damage to larger foes like Boss Bokoblins. They can also be used to clear out walls of breakable rocks or mine a whole batch of Ore Deposits in a matter of seconds. Just make sure you stay at a good distance.
7 Fire Fruit
Since the Great Fairies are focused on hiding away and enhancing Link's armor, you need to make your own magic. The first step to doing that is picking Fire Fruits. These red-orange bulbs are fairly common and can grow in a number of environments, though tend to prefer very green locations.
By Fusing these to your Arrows, you get another classic in the Fire Arrow. This is a precise way to set enemies and objects on fire without being too destructive. They're also quite useful when it comes to cooking, and you can eat them to restore your health in a pinch.
6 Muddle Bud
The Depths is a new map that's been introduced by the Upheaval and has been exposed by all the Chasms around the Kingdom. By diving in and landing safely at the bottom, you'll gain access to a whole new region full of interesting flora. Of these are the dark purple rose-like flowers called Muddle Buds which you can pick from around the large trees and mushrooms.
These things are like confusion in your hand and Fusing them to Arrows gives you Muddle Arrows. Hit an enemy with it, and they'll attack anything that gets near them. As you can imagine, this is extremely useful and entertaining when assaulting enemy camps and forts that have a large boss in charge.
5 White ChuChu Jelly
A recurring enemy in The Legend Of Zelda series is the ChuChu, Hyrule's version of slimes. These colorful blobs can thrive in any environment and will literally pop out of the ground to jump at you. Based on their color, they can hit you with elemental attacks.
If you're in cold regions, you can find White ChuChu and slay them for their Jelly. Attack this to your Arrows, and you'll end up with Ice Arrows that can freeze most enemies solid. While frozen, enemies are immobile, and you can hit them with all sorts of attacks until they thaw or shatter.
4 Puffshroom
Keep exploring the Depths, and you'll come across a lot of strange and curious things, including giant mushrooms. Growing around them are smaller versions called Puffshrooms. They're described as being bitter, so they can't be used in cooking but can be an ingredient in elixirs.
They also have an interesting effect when Fused to Arrows, turning them into Puff Arrows. By firing these at enemies or at an area, a huge puff of smoke is produced which can disorient them. This creates an opportunity for you to retreat, seek cover, or run in and find a good spot to continue your attack.
3 Keese Parts
Another recurring enemy in Hyrule is the Keese which are essentially bats. In the newer games, they've been redesigned to have one huge eye and protruding teeth. Like actual bats, they're frequently encountered at night or in dark spots like caves.
Defeating them will get you Keese Eyes and Keese Wings for your collection. Fuse the Eye to your Arrows, and it will literally veer toward targets as a Homing Arrow. If you Fuse a Wing to your Arrows, you can fire from greater safety as they fly farther becoming Flight Arrows.
2 Courser Bee Honey
Bees are a force to be reckoned with in real-life and in gaming with no shame to be felt should you succumb to their stings. Whenever Link gets too close to Bees, they will fly after him to sting him for a decent amount of damage. In Tears Of The Kingdom, you can find Bees swarming their Hives that can be found hanging from trees around Hyrule.
If you shoot the Hive down, you can grab the Hive and get away before the Bees can catch you. Rub the Courser Bee Honey on your Arrows and turn them into Stinger Arrows which will draw a swarm of Bees to whatever and whoever they hit. Bee Courser Honey is also quite valuable as food and an ingredient.
1 Dazzlefruit
Sometimes the best way to enter a battle is with radiance. This can be literally accomplished to a surprising degree with Dazzlefruit, with can grow randomly in the plains. These star-like fruits with tendrils have a very useful effect that is prized in numerous games: Creating a flash.
By Fusing these fruits to your Arrows, you can create Flash Arrows. Upon impact, they create a burst of light that blinds all nearby enemies. This can cause them to panic and swing wildly causing them to injure each other or set them up for follow-up attacks and traps.
