Alright, let's see what's happening:
@Kaneda_Shepard : All of your characters have survived!
@Darkstar8 : You don't add your Luck modifier to a Luck check, it is a flat d20 roll. Regardless, it doesn't affect your results this time. All of your characters have survived!
@DaBardsItch : I still need to know the marching order of your characters. Looks like your post is a little out of chronological order, which is fine since it's a good, detailed post! Now you'll need to roll to see who survives the wind.
@Mnrtoler : Henry can burn 2 points of Luck to gain a +2 bonus to his Reflex save and survive. Likewise, Deacon could burn all 8 points of his Luck and survive, but that would leave him with 0 Luck. A target reduced to 0 Luck suffers such constant, bizarre mishaps that he is effectively unable to accomplish anything.
@Qralloq : All of your characters have survived!
@DungeonCat : Thelma can survive by burning 4 points of Luck to gain a +4 bonus to her Reflex save. Mildred can survive by burning 5 points of Luck to gain a +5 bonus to her Reflex save.
@dominion451 : Still need rolls for your characters!
