How can I tell if I am doing enough damage?

[seekified]

I'm not sure which is better for 4+ mobs; Katon or Doton. I usually put down Doton first, then use Kassatsu and then Katon, but not sure if it optimal way.

As for this, you should do it the other way around. Doton is special - Kassatsu will make every tick crit for Doton's whole duration. So Katon > Kassatsu > Doton and then spamming Death Blossom is the best AoE you can do as NIN.

But yes, Stone Sky Sea is the only "official" way of finding out if you're doing decent damage or not.

That's not correct.
This makes only sense, if the mobs live longer then ~21sec during the doton time
Most of the time the mobs die earlier, so it's better to use katon

There are many ninjas who cast doton at boss mobs. which is completly wrong.


@Fina
You should watch some guides about your class and try Stone Sky Sea. So you will know, if your dps is high enough or not.
