An endgame build for Howler might look something like this: Titanic mag, quick reload, escalating resilience, lucky shot, point blank, superior stamina, vampiric burst (the bonus ammo would let you use your 3 twice without reloading even though the firerate doesn't add much), arcane surge, boundless spirit, superior duration, bullet resist shredder, mercurial Magnum.
Which definitely looks different than other builds haha.
