cards in hand and charity
 

Let's say you're left with 5 high-level monsters in your hand. No one wants them. Is the lowest level player forced to take them?

Also, for beserking can you discard those for the extra levels? Doesn't sound like there is any restrictions on the card that can be used.

If you only have five cards, you don't have any Charity to give. But if you DO have enough cards for Charity, you choose which cards you give away -- the recipient doesn't have any choice. (It's Charity, but it doesn't have to be NICE.)

Berserking: Whatever cards you discard to power this ability are discarded without any other effects; all you get is the +1 bonus for your Warrior for each card, up to a max of +3 total.
