Congrats, that's a hell of a haul. Hope you still have your Kusanali stash though...
So I played with Nilou for a while in the trial, I think I "get" it now. Her elemental skill and her normal attacks are the 'trigger' for which version of her elemental skill you want to use. If you tap elemental skill + any two attacks + end on a normal attack, she goes into water imbued slicing DPS mode. If you tap elemental skill + any two attacks + end on another tap of elemental skill, she puts out that water wheel that gives your party the Bountiful Cores buff and makes things wet. So each time you use her Elemental skill, you have to pick if you want to be on-field DPS or off-field Hydro generation and Bountiful Cores buff.
Bountiful Cores were decently strong, but that's in the trial where you can't trust shit. A few thoughts about her kit and her in general:
- Bountiful Cores buff is tied specifically to the elemental skill tapped variation of her elemental skill. You don't get them any other way, which sucks. So not only are you limited into using specific elements and team comps, but the cores aren't even automatic, and don't happen at all if you do the DPS stance.
- With her kit being designed with the above in mind, it's even more bullshit that they do the team limitation stuff. The fact that you have to pick between off field Hydro application (with no Hydro damage I'll add) and DPS mode should have been enough of a limitation to whether or not you can make Bountiful Cores. You can't Hyperbloom or Burgeon them anyways, so the limitation is just stupid and bullshit.
- Buff is too short, which railroads you into going for C1 if you actually want to get any use out of it. They probably designed it with the original duration then said "lets shorten it and make it a constellation lol!" Scummy.
- Cooldowns seemed long, but actually fit pretty well considering rotations.
Overall I like the mechanic forcing you to pick how you want to use her for that particular rotation, and I hope we see more of that. But all the limitations on her are needless and make her less fun.
