How to get the most out of Swallow Soul?

Ive looked around, and havent been able to figure out how exactly this works. Is the healing based on the damage directly before or after the first tic? Initially, I thought it scaled dynamically during its up time, but It doesn't, unless the FTC addon isnt working properly. tested it a little, but couldnt get consistant results, probably due to being kinda impatient. I think I was lvl 14 when I was doing this. If I cast it without using another ability for a second, it healed for 20 per tic. I tried casting it before/after stealth> concealed weapon, and usually id get like, 4 heals per tic, but occasionally, I could get 60, which was very usefully badass, as I had like 400 max health at that point. I couldnt figure out how to time it though, got annoyed and dropped it. Id appreciate any feedback.

Oh yeah-Also I wondered if the "excecutioner" passive from the assassination tree is worth it. It seems like it only refunds a small percentage of the cost of using the execute ability. After wearing a mob down to the point where id get the 300% bonus damage, I can kill them just as easily with a heavy attack, and save the magica anyway. I dunno, maybe it scales in higher levels or something. Feel like im probly missing something
