Another blessing Issue?

So, I got those blessings to choose from. The first literally say:

  • all heroes with MANA level lower than 50% HP
  • get 5% mana per turn

I know it is just translation problem (PL language). But I also wonder if it is F_up the same way as 250 HP heal blessing per turn which really heal once in 5 turns.
Anybody?

Depends on the earlier blessings chosen.

I try to “stack” my blessings.

If I opted for +10% mana generation, I will try to stack that. To make it 20%.
