Just messed around with ninjutsu nuking. 86 nin/41rdm with 340 skill, full hyoton: san, full hyoton+ damage, and some basic INT gear + HQ staves that I threw together quick.
In abys plains vs. EP plateau hare:
With Minikin + Kirin atmas total INT was 224ish; ni spells were 630 and 753 with tonic. Innin/Futae and hyoton: san did 1649 and 2035 (ice day proc) with tonic.
With Minikin + Baying atmas total INT was 185ish; ni spells were 702 and 813 with tonic. Innin/Futae and hyoton: san did 1794 and 2031 with tonic.
Not 100% exact on the int numbers because of the INT on aquilo's staff and I also don't know if the tonic gave int; i've never looked to see. The ni spell damage is from ones other than hyoton, I kept getting day procs and I have damage + merits so was hard to compare atmas. I was kinda shocked to see such high numbers, not sure how useful it will be but was kinda fun to play with.
