Poison, sand, burn damage?

any ranking among those damages done to the enemies?

i just summon 4star fura (dark) but i just realize her ability is same as jabar and gafar also dark which i also have…i just wanna use her for leveling to save my hero roster since i dont understand between poison damage and sand damage, any suggestion?

Not sure where you are reading poison at. Fura reduces max HP to all enemies by 100 and does 150 damage to all enemies. Jabar & Gafar reduce healing do damage to 1 enemy and do sand damage over 4 turns. So no I’m sorry Fura is not the same as the other 2

There is no ranking because it differ between heroes.

But as poison and poison won’t stack, variety is better.
