here's my [Hespar] hybrid setup! i haven't run into literally anything this beast can't handle, and goes to show you can make just about any melee do it's rightful work nowadays!
the heavy attack does massive radial damage with forced impact, slash, and knockdown, enabling very high burst damage in a pretty dang large area around you!

dreamer's wrath or opportunity's reach for exilus/tennokai, up to personal taste really!
riven flex slot is [Organ Shatter], you'd want to shoot for range, melee attack speed, and crit damage! negative is to taste, but i find it best to dump heavy attack eff./impact/puncture damage.
you can swap melee exposure for melee animosity if you're running a frame that has corrosive/armor strip built in, like [Hydroid Prime]!
highly recommend using with atleast x2 Violet Archon Shards (Energy max ^500 = +50% Melee Crit Damage for maximum crit shenanigans!

this is mostly just to show friends, but thanks for reading anyway :}
