so no chance for a Energy Adept to get the +4 other element card bonus(from Environmental Advantage), cause his nova is restricted?
Correct. As the rules stand right now an Energy Adept may use a max of 4 novas due to the Floating Heart Arena's Environmental Disadvantage, which means he may not utilize the Environmental Advantage.
+ First Blood: In the first two matches you may use 5 additional upgraded cards.
- Stubborn: You may only switch between two different decks each round.
losing upgraded cards isnt a change of the deck, right?
Right.
so its also possible to change (also unforced) the upgraded cards?
It might be helpful to think of it this way: decide on two unupgraded decks. During the first two matches you must use these decks but you may up five additional cards. The cards you choose to use upgraded can switch.
Btw I intend to discuss these clarifications with the other Event Organizer, The Mormegil. We'll make any rule changes and clarifications public before character sheets are due so keep an eye on this thread.
Thanks again for the questions, Antagon.
