Mafia 95. The Wardens' campaign against Urubaen.

It all depends on the order of the non-damage abilities. If you block the one with a higher Block than Mana Block, then Mana Block won't work. If the one with a lower Block, then Mana Block will have time to block.

So, Heroist and Tenshi are not Mana Block. Although everyone probably already understood that.

explain, I didn't understand why.

Well, you were attacked by one of the Mafia dragons. So, it's definitely not someone from the blocked players. It's a pity that the dragons can't be distinguished by their description.
