The Blitz Scenario Card reads:
"RULE CHANGES
All powers are 
Powers which were already  (or made ) cost 1 less Energy. (For Innate Powers and Power Cards cost 0, instead gain 1 Energy.)
When Exploring, once per board, add an additional .
If the Island becomes "Blighted", put 1 less  per player on the Blight Card."
My question is: when you add the additional , do you add them in the Land type shown or in any land of your choosing?
I played with the latter, because if it were the former the Scenario Card would look something like this:
"RULE CHANGES
All powers are 
Powers which were already  (or made ) cost 1 less Energy. (For Innate Powers and Power Cards cost 0, instead gain 1 Energy.)
When Exploring, once per board in the shown Land Type, add an additional .
If the Island becomes "Blighted", put 1 less  per player on the Blight Card."
I tried to find an answer in the online, mobile-friendly living FAQ, but it didn't have an answer.
