if you use a feat card once, is it gone or can you use the feat card again? like, if i use haymaker once, can i use it again next turn?

also, when using passenger, can you have the carried figure attack after the movement or does it follow the naat rule?

and can someone explain pulse wave a bit better to me? the way im understanding it as you attack all figures within half of your range ignoring all powers/modifiers/team abilities. and you roll the dice for each figure and do a click for each figure hit or do you do the printed damage?

and do battlefield conditions stay on the field throughout the entire game?

thanks for any help on these questions.

As long as it does not say on the card "remove [this card] from the game" you can reuse it as many times as you want.

Yes. All carried figures follow the NAAT rules.

You got it right except you only roll once and compare all figures using that one roll result. And Pulse Wave does replace the Damage Value with 1. If you use the Nova Blast Feat Card, it overrides the 1 Damage, and you will do damage equal to the printed damage instead.

Yes.

No prob.

unless there is only one character within the pulse-wavers halved range. example Nimrod vs Wolverine Wolvie is 4 spaces away from nimrod and the next closest is 6. Nimrod will pulse wave and deal only Wolvie the 4 damage.
