Perfect, I've tried that before and gave up halfway. lol
Expert mode is really only noticeable one the Gummi Ship, I never noticed any difference in the regular Heartless.
I have some options, though I'm not going through the game without healing, ain't gonna happen. lol
No armor items.
No Elixir use.
Goofy and Donald keep default weapons.
Use no Black Magic, Fire, Gravity, etc... (I hardly do anyway.)
No Special Attacks, Ars Arcanum, Ragnarok, etc...
No use of Scan (this one is a real challenge)
Little or no use of Guard (I sort of need it)
No Status Enhancement Items, AP Boost, Strength Boost, etc...
No Special Abilities, Glide, High Jump, etc...
If you guys want me to close to kill myself any further, you need to come up with them, I'll do all these and more. I'll put off playing it till we get them all in.
