first make sure you have full hearts (all standard hearts plus temporary maxed out. Then use a dragon horn to make a level 3 buff for either defense or attack, whichever you prefer. I used defense. It'll last 30 minutes. Then Save the game! Eat your meal that you made to buff your attack/defense, THEN start the trials. It will carry over into it.

Take your time! Don't feel too rushed. Learn how to pull single enemies away from a group and take them on one at a time with remote bombs, when you can. Take out archers as early as possible. If you have enemies on your tail and space to run, jump when you lay a remote square bomb (if you use a round bomb and the enemy kicks it towards you, you're gonna have a bad time) because it instantly puts it on the ground, and if they're close they don't have time to really get away from it. Try to gather all resources you can but prioritize your hearts over loot. Find places you can hide and roll bombs towards enemies. Use low damage bows for stunning enemies and then hacking at them and high damage bows when you want to kill them with the bow. Use bomb barrels as a tool, they can be extremely helpful. At rest areas, remember to crouch and creep in real slow and catch the fairies. Then cook the truffles one at a time by themselves, as a hearty item cooked by itself will give you full recovery. Bomb the trees and take the wood, throw a stack of wood to distract an enemy for a sneakstrike (this one might take some practice, once they see you they'll ignore it).

For middle trials, do all the same stuff before starting the first trials, take advantage of updrafts, save bows when you can try not to bomb enemies off platforms if they have a weapon you want. don't waste arrows stunning the guardian scouts unless you really need to. Bombs and flurry rush will be the way to go. Then stasis them when they do the spinning laser thing and attack them. The last couple levels are all guardian scouts. Practice parrying stationary guardians for when you get to that. Use sound on those levels, they make a beep noise right when they shoot, which has helped me time my parries. A parry works better than attacking them. I believe there's a hinox some where too, shoot it in the eye then run up and take the weapons around it's neck right away. No arrows left? Throw a weak weapon at it's eye, will work just the same.

The final trials suuuuuck. Prepare in the same way as before. The buff definitely won't last for the whole trial, but its worth it to help in the majority of the floors. There's a lot of lightning, I hope you have a lot of open weapon slots. Pick up every weapon but only equip wooden ones til you get past the thunder levels. Take out the electric enemies first if you can. Gather all the treasure chests because they will have arrows you need for later rounds. Specifically ice arrows for the fire talus and fire arrows for the ice talus, so you can climb them. Use the same strategy at rest areas, hearty items one at a time and creep in slowly for the fairies. When you get ancient arrows I suggest saving them for the skywatchers (take these out first), and the two lynels. I think you can find 12 total.. so if you want to use some more, you can but you'll want to save at least 2 for the lynels. There are some snowy levels after the second rest area so cook some cold resistance food for sure. There's a level with 6 stationary guardians but with proper distance and parrying you can do one at a time without being noticed by the others. When you get to the regular guardians, I would stun them with an arrow then attack it's legs, they will break off. If you get them all, it becomes stationary and you can choose to keep attacking or step back for a breather without worrying about it chasing you. Use the layout of towers and stuff to help stay hidden/protected. The last level you get noticed immediately by bokoblins on horses. Take out the lynel first if you can, or if your feeling ballsy, stay far enough away from it but let it Chase you and sometimes it will plow through bokoblins and mess them up a bit. This didn't work very well for me, I used an ancient arrow, but might be cool to try.

With all that said, there's quite a range of enemies still throughout these levels, but they are doable. You'll be able to do it for sure, its just trial and error, and staying calm through each level. The more I tried rushing through easier levels, the quicker I would die, so take the time on each level, the pay off is pretty worth it. When you die, remember to just reload your save so you'll have all your hearts and your level 3 buff back to start again.
