Some questions about battle.

[ditikos]

I've started munchkin recently and I've done some few battles and I saw the tabletop episode with Steve Jackson the other night that raised some questions.

First of all, once you declare that you are going to do a solo battle is that final? Can you ask for help anytime during battle?

Secondly the bargaining of help. Is the player actually required to ask for help, or the other players can offer their help as well (unwanted or not), for an exchange of XyZ treasures or items?

Thirdly, is there a limit to side items? Many say you can only have two and they say it's a "backpack" (that's how it was introduced to me during gameplay).

How many curses can be used in battle?
