Multiple effects simultaneous

[Trel Drasnek]

If I get a sickening critical with a thundering weapon, dc 14 fort save vs deafness on critical, does the -2 to saves from the sickened effect increase the dc from the deafness to 16 or do I need to wait for another crit for the increased dc.

First, you now have put Chef, from South Park, singing his "Simultaneous" song.

Second, there is usually a consensus, that if you can create two effects, simultaneous, you choose what effect occurs first.

Really, the rules don't quite cover this.
