If you are a summoner do you get the passive necromancy regeneration from damage caused by your summon/totem?

I've been playing Sebille as summoner and put every combat ability point into that so far (am on level 6 so I have 8 points in Summoning).

In a way I think you should as they are your summon so it is damage you caused but both Summoning and Polymorph are badly over-powered at the moment anyway.

I can put a point in Necromancy next level and fight someone but how can I tell where any regeneration comes from? I don't understand the combat log as it doesn't seem to give enough detail. It just says things like "Sebille regained 3 vitality". From what? Who knows.

If anyone knows (or knows how to test it) it would be great.
