Attacking with a Lifesteal minion when you have Bolf and Auchenai on board will trigger the Lifesteal damage on Bolf and your Hero

The reason might be that a trigger cannot occur inside itself (#891).
This won't happen if it's not Bolf himself but another minion that has Lifesteal (#840).

will wound your hero finally

This wording isn't exactly clear. What do you mean?

[Kybxd]

I mean that your hero shall never take any damage when you have Bolf but do take damage in this special occasion.

Could be fixed in next release

Same results with a regular Lifesteal minion, it doesn't have to be Bolf. (Pictures are same behavior as original video).

Game Mechanics Update – Different damage redirection effects can chain with each other, but each one will only occur once. Re-directed damage is applied before modifiers (e.g. Cursed Blade) and will only damage the final target once.
