Della (Iron Dobbin) is a 4 stars Defense character in Artery Gear.
Della is probably one of the best PvP units due to her RNG on her skill 2 passive, which allows her to counter attack when hit. Paired with a counter attack set, she can retaliate with an AoE attack (low chance to stun) to disrupt enemy cleaves in PvP. Her skill 3 also does decent damage and it can stun as well. Her skill 1 can apply speed down, which is useful.
She does need a lot of health, defense and some attack to compensate for building her a bit slow. So each time she gets hit, there is always a chance she will do damage. Since most cleavers are usually squishy (such as Grace, Ruri etc), they will die to Della easily. She still has trouble with red units though, so she isn't completely invincible.
She does have very good team synergy with units like Acacia, Feidy or Iberis, which are units that can either provide damage mitigation or shields. Add on some tanky healers like Morris, Diancht or Hearin on defense PvP and you have a nightmare team to deal with.
Do remember that she is not very beginner friendly as you do need very good gear to get to those godly levels in PvP. I would only recommend building her once you can farm difficulty 9 hunts with ease.
