Pasi, were you fighting the Original Venril Sathir or the spawned VS for epics?
That log doesn't look right for some reason, he is attacking WAY too slow.

This one is kinda long, just listing successfull attacks that were logged. Can't recall for sure but I think thorns go off with Rune on? Don't let this fool you too, his attack speed is 2 seconds but his misses are not logged. Excluding bashes and kicks because I don't know the damage interval on them. Attacks in bold are not counted because Ewandor partial runed them -- I think this is correct, NPC cannot proc on attack that is partially blocked by a Rune??:

20 successful attacks logged
Processed Deadly Lifetap on 10 out of 20 attacks that were not partially runed
I would say Venril Sathir's Deadly Lifetap proc should be somewhere between 50% and 66% on successful attacks (Kick and Bash included). This would make Venril Sathir proc about once every round (every 2 seconds without Rune). Two Ripostes from the front and you are taking a lifetap most likely.
