We just finished S-4 encounter in the GW rulebook, the one with the Beta Moss and Blaash. Any PC adjacent to a Blaash experiences an aplha flux on a roll of a 4or less on a d20, in beta moss, its 5 or less. What a wild chaotic encounter. One PC, Sputnik, went experienced 3 alpha fluxes in one turn. He first rolled a 1 on a overcharge on, which should daze him after the effect, adrenaline something
but he also changes out his alpha mutation. Also, on that turn he rolled a 4,5 simultaniously on a close blast attack, telekenetic wave
I think, I just narrated the whole thing. I also negated the dazed effect for missing the overcharge. But I think I will, apply the effect in that case, in the future as well as narrate and change out the alpha mutations. Anyway it was lots of fun for our group and has us all saying "Flux happens!"
