Conferring Blessings

If you have a Gunnthra, any cavalry team she is in would benefit, as would any team she contributes to.

If you do not, then put them wherever like I did (still slapped them on a full cav team).

Yesterday I "asked" my Athena if she wanted to be on my wind team. She "told me" that she didn't want to be part of the "fart team."

On another note, units with Iceberg and Glacies would benefit from hanging out with Gunnthra.

Like TG15 said, don’t over think it, if you have a cavalry team and Gunnthra, put it on 3 cavalry units you want to use and go.
Otherwise, any units that have good resistance or are used to tank magical attack’s (distant counter users).
I gave it to Reinhardt, Brave Lyn and Sigurd (took Gunnthra as my 4th)

All u can really do is ask what units go with the legendary heroes u HAVE. The stat boost are hero dependent not blesing dependent.

And when in doubt just use a unit that can stand to benefit from ANY stat. Like dc units. And build a good balanced team ready to swap a unit for a legendary one when u get one

Ps u dont even state if u have gunthra in the first place....that is kinda relevant
