Hm yes, new Neutral Special. Note that all Neutral Special changes are new from Beta.

General:
~ [+] Probability of losing Copy Ability in a single hit reduced by 33.3%. It's now equal to ⅔ of damage taken in a single hit.
~ Example: if Kirby gets hit by a move that deals 15%, the probability of losing copy ability on that hit is 10%, where it would previously be 15%.

Copy Abilities: ---------------------------------------
~ Roy (Flare Blade):
~ [!] Correctly repositioned hitboxes to the left arm and sword (because wtf was going on)
Before:

After:

~ Lucas (Offense Up):
~ [!] Fixed an issue where the sound for charging Offense Up was not playing
~ [!] Fixed an issue where Kirby would continue to have the PSI effects if the Copy Ability was lost

~ Ridley (Plasma Breath):
~ [!] Fixed an issue where Kirby would T-Pose when charging the move if Kirby changed from air to ground, or ground to air, which consequently also allowed it to charge infinitely.

~ Dark Samus (Charge Shot):
~ [!] Fixed an issue where if you pressed Shield in the air to cancel Charge Shot charging, Kirby would transition to airdodge instead of normal fall.

~ Banjo & Kazooie (Blue Eggs):
~ [!] Disabled the ability for Kirby to perform Forward Tilt out of Blue Eggs.
~ [$] Added sweat effects for when Kazooie's Blue Egg Power is decreasing.

~ Palutena (Colorless Attack & Auto Reticle)
~ [R] Reworked to an Energy System. Kirby gains 1 Cyan Energy point when he lands an attack with any of his normals (except Neutral Air, Jab, and Dash Attack), and 3 Cyan Energy points when he lands Colorless Attack, which still comes out on Frame 7.
~ [R] On frame 14 of Colorless Attack, if Kirby has at least 3 energy points, he will proceed to use Auto Reticle. The bullet consumes 1 energy point when it spawns. Since Kirby gains 3 on hit, this will always result in Auto Reticle and consume that gained energy if a target is found.
~ [R] Kirby can hold up to 6 Cyan Energy points, and can perform Auto Reticle twice. If Colorless Attack connects when Kirby has 4 or more energy points, Kirby will be able to use that extra energy. If it is not consumed, it will be lost and reset to 6.
~ [-] FAF: 33 -> 43
~ [-] Can no longer be dash or jump Canceled on hit
~ [!] Modified Auto Reticle Stats
