Thus, I think I can safely say Rumia's always been good and I'm the only one that knew it. :V
Lots of NND videos of this game use Rumia... so yeah.
In a similar way, Wriggle's turned out to be way the hell stronger than anyone thought. There's a few reasons:
1. Any attempt to calculate damage (Read as: Mine in the past) was limited to "until she next attacks", which makes her damage look mediocre. If she only applies it once every rare while however, the damage adds up in much the same way of an 'in, out, rest' type nuker. She actually does better landing some poison, and then being swapped out for a while before coming back in to reapply it.
2. Her damage potential has been shown to be pretty high on bosses. A 440k boss was calculated to have taken ~40k damage from a
single use of Comet on Earth over the course of the whole battle - and that was a boss with good PSN resistance!
3. And speaking of PSN resistance, almost no bosses in the game have it (I think the only one completely immune is
). Even the final boss has only a tiny bit of poison resistance. Hell,
even the 30F superbosses don't have PSN resistance.
Finally, funny how a +3 multiplier to Nitori's damage formula on one attack turned her into a godly attacker.
Extra Finally: You're now aware that Grand Patriot's Elixir has a ridiculous small delay for the amount of buffing it does to Reisen.
