Dorcas Build

It's a really good build and don't need to change anything except for the seal in some situations.

if your in teir 20 I recommend to change the seal to deflect magic if you are worried about rein cause normally rein does the moonbow quickend pulse combo and to counter it it's either guard or deflect magic. but if you are in the higher rankings of teir 20 then distant def is the best seal for him since reins are rare at that point.

if your not in teir 20 then it's more than enough.

If you’re wanting him to be a mage fighter, deflect magic 3 will go a long way. But as a general ranged fighter, distant def could work just fine.

Soleil can do fine as long as she initiated the attack against green mages, and distant defense would be fine for Dorcas tanking and killing Reinhardt, and his bulk would be sufficient for dealing with lances. I think you have the start of a good team.

Of course it's good! Dorcas has decent enough Res to build off of, but whether you run Steady Warding or even his base Fierce Stance he's an amazing unit.
Although if you ever pull a +res -spd Dorcas, merge this one into him as it will help him proc infantry pulse more.
