Help I've been Nerfed and can't get my damage back up :(

[Psycofang]

I main NIN now and lost all three of my DoT abilities, Sharp Fang, Mutilate and the Ninjutsu skill that does AoE earth damage that I can never remember the name of. That is a rather substantial loss in DoT

You still have shadow fang which is a DoT and you still have Doton which is a DoT.

You only lost mutilate.
