Ahh, the results of curiosity and insomnia...
I found myself curious about Vampirism's add effect. So I went to test.
Rigged some GS code to not let my HP/MP/TP ever be full, and went to town on an Apex crab. Melee'd it till dead.
Test 1.
Normal TP gear.

Now, I know I've seen a better proc rate than that in this thing just using it as a piercing wep vs that Zdei warden NM. SO I stacked up some macc in my TP set to see what would happen.
Mob: lvl 128 Apex crab
MACC+ 268 in gear. previous set had +25 already so 243 difference
Once again, melee apex crab till dead.

So, we've gone from a 10% Proc rate to a 95% rate. Neat. Good evidence on the effects of macc on added effect proc rates, if anyone was wondering about that.
HP and MP drain are the majority of the proc distribution at 45% each, leaving TP drain to proc 10% of the time.
HP and MP are very static almost always draining 5 hp/mp. TP drain seems to vary from 0~100. Not sure if it drains some % of the mobs TP or just randomly selects a value in the range and drains if it can. The avg TP drain was 49 in a 0~100 range so even distribution seems likely.
Also interesting is that the TP drained values are very nearly the same despite the macc different. seems like while the proc rate is vastly influenced by macc, the proc amount is not.
It's too bad this doesn't just drain TP. it'd be pretty amazing if it did. even with the macc issue, I think you could completely shut down a mobs TP moves if it always drained TP. Not to mention, you know, getting a ton of extra TP.
