Hello there I have been trying some diffrent builds and I would like to have you looking in to this one. (sorry if someone allready posted this)
The idee is Fresh Air build + boons + lightninghammer filler.
So you start out in Air use glyph of storm, conjur lightninghammer, use overload switch atunment, crit and back to Air, Where you can use lightninghammer (or heal or utilitys) while you wait for overload. Then just repeat this.
From what I have tried the damage is insane in groups.
One thing with this build is that it makes your choice of weapons obsolete,
even if you run out of hammer (somone els picks upp the spare just fill in with utilitys or some quick fire fields. the hammer will soon be off cd)
