What can I play during combat?

[sinnott7]

I am very new to this game (just played once with my kids) and I am confused about what you can and can't play or do after starting combat. After reading the rules I thought that you were restricted to only using the items you were carrying; in other words you cannot use anything in your hand, period. After viewing the flash DEMO and your comments here I see that I am wrong. (In the DEMO a "baby monster card -5" that was in "my" hand was used during combat and you state in this thread that you can change your class even while in combat).

Please clarify this for me.

Thanks! :)
