Honestly I think it should be the ERA accurate 4 seconds. However some people feel very strongly that 4 seconds para blows are OP. That being said, 2 second Para blows make fencing far too weak. Perhaps we should agree on 3 seconds and see how that runs. however I feel very strongly that 2 seconds is too short
para blow doesnt even seem to last one second on monsters when i use it here. u have a 12.5 % chance to re-parablow someone on the next swing if you have gm anat (according to the numbers ive seen on this site). but really that person will be running away as sooon as para blow wears off.
The duration for paralyzing blow was increased to 4 seconds, from 2 seconds in today's patch. Additionally, a mechanic was put in place to prevent "stasis-hits" which potentially could permanently lock a player into paralyzing hits. You will no longer be able to perform a paralyzing blow if your opponent is already under the effects of paralyze. Patch 18: viewtopic.php?f=14&t=621
