I just have 2 questions that I want ot be sure on their rulings.

One: If a card (without the keyword: Shielding) says, "place 1 shield token...", can this token be placed on an already shielded card? I assume yes, but am still learning the games' rules.

Two: If a card has the "Action" keyword without any "limits", can I use that action multiple times in the same Action Window? Again, I assume yes, but want a clear understanding.

Thanks, in advance, for you answers.

One: only if it specifically says you can place a shield on an already shielded card, otherwise you must abide by the rules that say max 1 shield per card.

Two: yes, as long as you pay the cost stated within the effect each time.

I am wondering where you found the "max 1 shield per card"?

The rule on pg 25 is for the Keyword "Shielding", not for the shield token itself.

Edit for spelling.

Shield tokens, pg 23.

Don't know how I missed that. Thanks for the answers.
