Offensive oriented Fjorm

I put on her vantage and moonbow. On A swift sparrow. and close def seal. So far I like it. I know it's not the best build but till I get better fodder units, this will do.

I’m at a loss with her, don’t really know what to do. I’m using L&D3 with Iceberg and she is good, although mine is +Spd. I would say her best build might be Steady Breath+QR3+Iceberg/Glacies. It’s really high investment tho. She is one of the heroes that can nuke on the counter, like the Black Knight. Also, she is perfect for summoner support.

What do you think her best build is?
