The game problem

Hello, I have been having a problem with game mechanics for a long time (about a month). Namely, she is associated with the arch-witch class "Blood Mage". The clumps of life from the passive skill given by the game simply won't spawn, which is why the game experience on this character has turned into a natural torture. The health for the spell is removed, but the blood clots do not appear. I've already tried all the options. and I reinstalled the game, and rebuilt the build to maximize the passive skill, and checked my chances of a critical hit, nothing helps. I would like to solve this problem.
