.paralyzed
From WikiManual
This sysvar will return 1 if you are currently under the influence of venom.
NOTE: EricL finds .paralyzed will be a positive number indicating the number of cycles remaining before the venom wears off.
Also ... .paralyzed is not included in the Sysvars chart, nor is it part of Sysvars2.21.txt.
Anyone have any info to help clear this up? Griztalk
