Sorry if my commentary is annoying. Not sure if I'd recommend this build. I love Steel skills and I love ballista totems, but it ended up only feeling ok. Awakened Arrow Nova is the best for boss fight but it sucks when the bosses move. I might slightly reconfigure this build slightly and try out Arillery Ballista instead using Wilma's
