I have never been a fan of the Nightblade skill “Blade Barrier” as it locks you in place and even though immune for the duration you can do nothing much except drink a potion and wait to use a movement skill to retreat. As a defense or protection skill there always seemed to be better alternatives.
In this experimental build I am playing with at the moment, (not designed to be an end-game build, but doing pretty well at the moment and is fun to play), I have focused on Doom Bolt and any items that give Chaos Bolt or Doom Bolt as auto skills on items. eg.
Also items that have suffix of “of Voidfire” that give
With many items like this equipped and a good movement rune like “Rah’ns Might”, even 1 point in “Blade Barrier” can become a nice offensive attack against big monsters, even end level bosses.
I basically throw the “Sigil of Corruption” and “Solael’s Flame” on the boss close up and then activate “Blade Barrier” while spamming my movement key in another direction. Very fun to watch the boss take extreme damage from the chaos and vitality bolts amongst other devotion skills that gets triggered. Once the skill has elapsed, I will be at a location that i was spamming on my movement skill and can launch my main big damage Doom Bolt skill, which is usually enough to finish most bosses off, if they are not already dead by the time I retreat from the Blade Barrier attack. If they survive, just rinse and repeat main Doom Bolt kite attack and when “Blade Barrier” back off cooldown attack close again.
Nothing groundbreaking, but nice to be able to play with a very underused skill and have fun with it.
