Help with S!Elise

I think a Bladetome build could still work on her. With -Atk IV, she has 33 attack, which can still be worked with. Maybe make her into another Nino with Fury + Desperation?

That's really the only thing I can think of. Her defense is garbo, and her res stat isn't all that great with a neutral res stat. So yeah, Bladetome is probably your best bet.

I'd say Blade tome is your best bet. She still has plenty of attack imo and Blade tomes don't really care about -atk. Pretty much what you gave her(you know, give her Fury 3 instead of 2 whenever you can and all that stuff). Threaten Res seems fine as long as you manage to activate it without risks. If you don't feel you can use it as well as you thought, her allies can also run Threaten Res. Same with Threaten Speed. Just buff her as much as you can and start nuking people.
I'd say Desperation is better for this build though, so take that into account.

However, since yours is +def, Gronnraven seems pretty decent for her if you need a metacheck. Raven+TA+Bowbreaker works like a charm, and she seems bulky enough to perform well. This way you also don't really have to care about the -atk because she'll still have enough to counterkill both Brave Lyn and Reinhardt.

You can also consider Gronnowl and try to use her to duel ranged units, in which case Fury is probably your best bet because you can get up to +9 to every stat(also +2 HP if you refine the tome).

Gronnwolf can work as well if you're seeing to many cavalry teams in your Arena/Arena Assault runs. -Atk hurts a bit here because you're doing "effective against" damage, but I'm sure it'll still be fine(she probably won't kill reds, that's all, but it's not like she will kill them anyway, unless she's +atk, maybe). I'd still choose any of the other tomes, though.

Eh, i really really don’t see this working
