Here’s my Miko Support build I’ve been using lately.
I cover the skills, helix, and some gameplay where my sole focus was to keep my allies in the fight.
I’m really torn on the lvl 6 and 8 choices for helix. I think the mutation at 6 is strong as is the “do no harm” side. For lvl 8 I really like both of them and I just can’t decide whether 30% reduction is better than a +5 additional seconds duration. I think the +5 second duration wins because you don’t have to be channeling your beam.
