This would disrupt the balance, gentlemen. Besides, mana is not consumed during prayer. Prayer itself is a useful ability.

This won't disrupt the balance if approached thoughtfully – a scream of terror that enhances the banshee's scream also disrupts the balance, doesn't it?
+10 to attack and defense, +5 to block – this is just an example; naturally, these numbers are taken randomly and need to be more precisely determined while maintaining balance.
In principle, I also liked the idea of applying a buff to a unit, but instead of a second strike, something else should be applied if we go down that path.
