Liquid Metal Slime killing. Good exp.

Yes but it's so difficult and it's not the metal King Slime. :D

I remember the first few times I met them in Dragon Warrior 1 they confused and annoyed the heck out of me. Then I killed one and was like "Aaaaaaaaaaaaaaah! THAT'S why they're so fast." while the screen continued to tell me all the levels I'd gained.

if i were they i should be beating the shit of that damn slime
