Blood Mages; Vitality Siphon, doesn't work.

From what I can tell, it looks like they're having a lot of issues with the passive tree in general. Respecs not happening, ascendancies not triggering, and so on.

On that note: quick bug report on another blood mage ascendancy part: I once respecced out of lifeblood because I couldn't bear that insane HP cost in a boss fight, and it resulted in the support gem I had slotted onto it to disappear. The tooltip for it is also very weird when you try having support gems, because the skill is always on no matter what, but it will turn up in the skill tab as if it's turned off because of spirit requirements if you try using other skills that take spirit. Even if it should add up to your max spirit it can still happen.

add me to the long list of folks who took blood mage purely for this only to find out it doesn't work with Contagion, Essence Drain, totem or the DoT upgrade from curses (basically any of my damage)

would it really be so difficult to add the word "hits" to the description?
now i've gotta spend 14,000 gold to get rid of it and essentially have no ascendancy, because it just isn't worth having the downside of spells costing health when my spells can't heal me.

please could it just heal for all spell damage?
the entire reason to play a blood mage is to cast spells for health and then heal for damage, but nothing in witches kit causes healing.

The tooltip information for Leech specifies that the damage is from Hits, so the information is there but buried. IMO it could definitely be more clear but, more importantly, the combination of being forced to take Sanguimancy and the fact that this particular leech ability is locked behind an Ascendancy and therefore should be build enabling, and a whole subset of the Witch skill gem damage is DoT while the other subset is mostly Minion (and therefore not spell damage), it should absolutely work with DoT damage. It's really dumb that it doesn't.
