have you promoted the Askr trio?

I promoted Sharena over a year ago and enjoy using her in Arena Assault, but I haven't touched Alfonse or Anna unless I need them for quests, so they're still at 4*. They may be slightly better with the refines though, especially Alfonse.

I have a long time ago.

Yes, I have and they're very good for what they are. Alfonse has similar stats to Ike, without the DC< Sharena is a few stats below Nephenee, and Anna is similar to Titania without the movement. In short, they're very good, and with Alfonse getting brazens, Sharena getting bonds, and Anna getting to warp around, it's very worth it.

Yes, they were in my first 5 promotions to 5*.
1.- Rein
2.- Cecilia
3.- Alfonse
4.- Sharena
5.- Anna

for me i have kept them at 4 star

Nope lmfao, IS has to do a lot more than give them dinky weapon refines to get me to use them.

I have played since launch, and I still have them at level 1, 3-stars. I don't really plan on using them.

I've done them all but I can't say I use them much, Anna comes out in AA but I won't be refining any of them. It does help when we get quests for GHB of use X to defeat Y but there'll be f2p guides using them at 4* anyway.

I 5* them long ago, they are very usefull to me as i don't pull that much on new heroes banners, they're helping me to stay in tier 20 for so much time (more or less for a year)

Anna I promoted some time ago. She wins against non-guard Nowi quite consistently with slaying axe + iceberg.

Alfonse I will promote at some point, and probably Sharena also. Still need to figure out their builds. Alfonse has a bad refine, but the brazen atk/def is super good. Sharena is probably harder to play, but it's still a good upgrade.

I 5 starred all three a long time ago. Mostly to make quests easier, but also if needed for the arena. For me, the feathers would be much easier to come up with than the divine dew. I have a long list of heroes to refine, since there are so many weapon upgrades by now, so the Askr trio will have to wait.

Already did it, all of them since like the beginning. Don’t really regret it, don’t really use them

I have promoted all three and I would say that they are all worth promoting at some point. They're often used in GHB and BHB missions so having them at their peak helps aid in completing those challenges. They're also great budget options for Arena bonus units. Heck, I'm not even a budget player and I use them in the Arena. The recently added bonus units buffs work wonders for all three of them and make them all surprisingly tanky (even Anna).
