[HoMM V]9 Race - Swamp! Is it needed?

I suggest adding the following skill to the game: LIFE-GIVING BLESSING - GUARDIAN ANGEL - DRAGON'S PROTECTION (corresponding to the deity they worship). SKILL BONUS: If only 20% of your army remains, a dragon will descend onto the battlefield and kill 70% of the strongest unit and 50% of the second strongest unit.
