Kingdom Hearts 2 Final Mix (PS4) - Mushroom XIII (LV1 Critical) *No Stat Boosts*
So for those not in the know about LV1, this was considered for MANY years to be impossible. Three of the Mushrooms were simply not feasible with LV1 stats so people were forced to use Strength and Magic Boosts which ruin the entire spirit of the LV1 challenge. However discoveries were eventually made to make them possible and finally make the Gold Crown obtainable on a True LV1 file.

There are 2 reaction commands here, a normal Reversal and a Quick Slide RCF afterward. Once you Quick Slide, quickly short hop and do a single attack. You can only hit the mushroom 9 times each dodge so you need to time it right 11 times for max score.

Very easy, just Reflect the bullets and use Stitch and Ethers to restore your MP.

Equip all your Draws including Draw Ring and Follow the Wind. This one is easy on Critical thanks to the bonus Draw abilities.

Using Berserk Charge with Wisdom may be fairly slow damage wise but it's extremely safe and keeps you away from the Mushrooms effectively.

One of the "Impossible Three". Shouldn't come as a surprise this was impossible for a long time considering the DPS required to kill this thing. What was basically found was that by spamming Final Form's Glide while holding forward, Final Form's auto attack would cause repeat damage with every press. However just doing this isn't enough, you need enough Strength to break through the world's minimum strength floor. The best setup to do this is Fenrir, a 6 Str keyblade and 4 copies of Full Bloom or Full Bloom+. If you are really good at button mashing, you can get away with not having a perfect setup since your mashing speed influences your damage.

This one is about the main three elemental spells. Simply use Fire when in a circle, Blizzard when in a line and Thunder when spread out.

Second of the "Impossible Three". The strat for this one is simple, short hop and Reflect over and over again. There is a rhythm to it and it's pretty tough to time it perfectly every time. When the Mushroom is about finished, you need to throw out a Thunder because Reflect takes too long to explode. What sucks about this one is that you need Magic for it and the keyblade with the highest magic of 7 is locked behind this minigame. Without it the best is Fatal Crest with 5 and other keyblades with 4. This thing is just BARELY possible without Winner's Proof and you need 4 copies of Shadow Archive or Shadow Archive+ for it.

Considered by many to be the hardest Mushroom. The reason people have such a hard time with this is that they try spamming one strategy the whole time but that doesn't work. Around 60 you need to be prepared to change up your attack since he jumps away from your. The way to do this is by going into MP Charge and timing when you start so your MP comes back between 60 to 70. Start by spamming Horizontal Slash and then doing normal attacks when it jumps upward. The moment your MP comes back, use Donald's Comet and keep attacking. If the Mushroom jumps away, stop with Horizontal Slash while using Comet to keep it airborne and do the basic attack since Aerial Spiral will get you close him again.

More Berserk Charge. This doesn't always work but it's the most consistent I found. Remove your MP Hastes and Full Bloom+ accessories and just mash out Horizontal Slashes.

Last of the "Impossible Three". Same strategy as No.5, equip your best Strength gear and mash out Final Form's Glide.
8:15 No. 11
Pretty easy, go Final Form and go crazy with the air combos. When the Mushroom jumps away, use Firaga to bring yourself to the ground with little lag so you can jump and start again.

Simple strategy but difficult to do. With Berserk Charge and Wisdom Form you can effectively just tap the lock on button while sliding back and forth hitting the Mushrooms as you pass them.

After getting the items, I show off the gear I have including the 4 Full Booms and 4 Shadow Archives required for this. I also show that I am still at base stats with no boosts other then the 1 point in strength from the Struggle Bat at the start of the game.
