I feel like the Askr Trio have so much potential (especially Sharena) but its had to build/ use them because of their gen 1 stats and lack of merging. I wish there was some way to bring them up to date with current gen stats like a merge stone or just putting them in the summoning pool. IDK, it’d be cool to actually build them imo.
They are usable in any mode still. I have built them for arena scoring and those builds still work pretty fine. I also gave Fjorm atk spd bond 3 seal, double rally and good to go.
Sharena can be a serviceable high arena emergency bonus unit with double Spd/Def Bond as well as Brazen Atk/Res seal. Her stats become very well rounded with full +6 field buffs
