Source: Marianne - Starting skill.
Immortal Tsar's Curse is a spell that inflicts 50% ATK Down, MAT Down, DEF Down, and MDF Down to all enemies for five turns.
This is an extremely powerful debuff spell, possibly the most powerful one in the game. As an enemy spell from Gloomwing it is extremely debilitating to the party, and you should try to kill her before she can use it, or cast some of your own buffs to try and mitigate its effects until you can ride it out. As your own skill from Marianne being in your party it makes fights even more lopsided than they already are with how overpowered she is.
As the description of this skill indicates, the Immortal Tsar it refers to in the name is Marianne's father, Koschei. It is peculiar that Gloomwing gains this skill from consuming Eric(a)'s blood.
The following enemies can cast Immortal Tsar's Curse:
- Gloomwing (Extract Blood used on Eric(a))
