Munchkin Zombie: One Time Use Cards (in hand only?)

[bensrpgpile]

Hi All,

Munchkin Zombie Question: Getting confused on some item cards and whether they have to be in my hand or can be sitting out in front of me face up...

Q1: An item with no designated slot. Example: Wishing Ring. Do I have to keep that in my hand until it comes time to play it or can I just keep it face up out in front of me until I need to play it (for when I get cursed)?

Q2: A combat card with no gp value. Example: Roller Skate (used during combat, +3 to either side, use once). Do I have to keep that in my hand until it comes time to play it or can I just keep it face up out in front of me and call out its bonus when I need to play it?

Q3: An item with no slot designation. Example: A Flypaper Necktie +3. I get to keep that out in front of me as a face up item, right?

Q4: An item that has a gp value and one-time use. Example: Lighter Fluid or Bottle of Acid. Do I have to keep that in my hand until it comes time to play it or can I just keep it face up out in front of me and call out its bonus when I need to play it (and then discarding after that)?

Q5: Something with no gp value or slot. Example: +3 Bonus on Fire. Do I have to keep that in my hand until it comes time to play it or can I just keep it face up out in front of me and call out its bonus when I need to play it?

Thanks in advance for any help/clarification you can provide,

Ben
