Well, i think you're right.
Chain attribute are way too strong if the legion deck use it.
And no comment on loses 3 health point if played then.
So, i think, this the final version. Version 3.3
and here if you can't read the image
Loses 3 health point. If opposing character is :
Mage : Spirit +X and next opposing spell is discarded.
Warrior : Defense +X and next opposing action or item discarded.
Marauder : Attack +X and opposing character attack reset to printed score.
Priest : Heals X and next opposing Theurgy is removed and played without restriction.
Other classes : -X damage suffered and all other character suffers 1 to 5 direct damage.
Where X equals 5 minus each classes opposing character have.
This card removed from the game at the end of the fight.
