Mass Possession...
So this Peril of the Warp manifested itself at the end of our last game session.
We wrapped up the game after a somewhat heated debate about the exact effects:
Mass Possession affects everyone withing something like five to ten d10 meters in all directions, and lasts something like 2d10 rounds. In our case, we rolled out fifteen rounds.
At the start of each PC's turn, he/she must test WP or fall to the ground fighting off the possession. Failing this test gives the PC 1d5 Corruption Points.
So how does this work? Does this mean that:
1. Right away, everyone makes their WP save. If they pass, they're fine. Otherwise, they are prone, getting 1d5 Corruption points and cannot do anything for fifteen rounds?
Or does it mean that:
2. Every single round, each PC must make their WP save. Regardless of whether or not they pass, they must test again the next round until the effect wears off (fifteen rounds). Essentially each PC has to test their WP FIFTEEN times in a row. That means that a really unlucky player could accumulate 15d5 Corruption points. Holy crap indeed.
What is the correct way to handle this horrible effect?
