wew... i can only make the mobs dead when you make them fall... though you'll get a bad in the star.. and there are mobs which i can't kill because of the "super armor, and Fall Recovery status." and here are the mobs that can't be killed by this because they don't fall...
Bossess:
Harpy,Lich, Paradom, Partusay, Basilisk, Gardosen, Kaazeaaze(sorry if wrong spelling), Cyclops, Stone Golem(forgot the real name), Dark Armon, Octus, Renaisen, Zen...
i've only set them to die at 999999 HP and when they fall, because i don't have the time, to get there HP's correctly. and i didn't have to change the .crc file.
wish this would help a little...
