Mafia 100. Sylvan: Tree of Life.

Does this feature apply to execution/petrification?

Hmm. It applies to execution, but not to petrification... essentially, the player doesn't die; they just turn into a statue, so logically, it shouldn't apply.

I didn't know that the Warlord was a lone unit.
By the way, regarding this negative trait. Is it blocked?

This isn't that kind of redirect.
It depends on the order of the negative traits, but I'll try to place it higher up.
