Kingdom Hearts III

• Switching key blades while yours is transformed will pause the timer and let you pull it back out, fully transformed, at will.
• The default gummi ship comes with a weapon that doesn't fire until you release the shoot button. You can take out enemies way faster by holding the button until you see the lock on and releasing shoot than just holding the button the whole fight, even after upgrading the ship's guns.
• Early in the game, you get the ability "MP Safety". It costs 0 AP and makes sure you always have magic up for Cure. If you plan on using spells only for damage instead of healing, it's not worth equipping.
