Sister of the Reaping Moon question

[Ascaloth]

So, as a test of Xoti's unique Monk class ability to gain Wounds upon kill, I gave her the Saru-Sichr morningstar with the Death Sentence enchantment, which gives a 5% chance to instakill a Near Death enemy every 12 seconds.

 

I put her in a few fights, and it seems like enemies killed by the Death Sentence tick does give Xoti Wounds... but I cannot be sure, because the combat log is rather too vague. I can't really tell whether an enemy was killed by Death Sentence or otherwise by Xoti simply bludgeoning it to death, and if it's the former case, whether enemies killed by the tick does proc the Sister of the Reaping Moon class ability to gain wounds.

 

Does anyone here know for sure? Anyone who can dig into the backend code and determine which is the case?
