is an all conjuration build viable? is conjuration build doing good damage, clearing pit tier 80 easily?
i would answer it “yes” and “no”.
for the “yes”, conjurations is helping to do more damage by causing vulnerable, stun, chill, freeze, and stagger a boss. as long as the enemy doesn’t move/ boss is fainted, no matter how strong they are, you can cut them down eventually.
as for “no” part, conjurations does not do good damage by themselves. they are more like an ‘utility’ paving roads for your core skill to do damage.
so, “all conjuration build” in my opinion is not viable.
