Disclaimer: Different enemies have different breakbars. Following info only applies to standard dungeon/fractal bosses.
Since raw values are not known, I will use percentiles (total strength is 100%). The breakbar ticks every 0.24 seconds recharging 1.2% (5% per second).
Breaking the bar stuns and increases damage taken by 50% (both direct and condition) for 5 seconds and gives control immunity until the bar fully recharges (20 s). This means +12.5% party-wide damage if you instantly break it after recharge.
Long launches (3.32 s, -55.3%): Wild Blow, Updraft.
Pulls (1.5 s, -25%): Scorpion Wire, Into the Void.
Short transform (3 s, -50%): Toss Elixir X.
Long transform (10 s, -166.7%): Signet of Humility.
Other facts:
Sigil of Paralyzation works (increased stun duration)
Pull distance doesn’t matter
Enemy actions (attacking / movement) don’t matter
Other enemies (compared to fractal bosses):
Mordrem Guard Punisher: Bar 16.7%. Regen 0% per tick. Breaking causes 5 s stun and exposed.
Champion Mushroom Emperor: Bar 100%. Regen 0.24% per tick (1% per second). Breaking causes 3.75 s stun and 15 s immunity (recharges 1.6% per tick, 6.67% per second).
Fun fact:
Gale is 2x 2s KD, that’s why the 66.7%.
You can notice it in open world mobs and pvp npc’s. It knocks them down twice, each for 2s.
Great design….
However, can anyone confirm if the distance that Point Blank Shot is used at will effect break bar %?
Also, I know that skills like Surge of the Mists (rev staff) and Tides of Time (chrono shield) are a bit different when they hit an enemy with a large hit box since it pretty much registers as multiple knockback/stuns. Does anyone know which does more breakbar reduction in an optimal situation where an enemy has a huge hitbox?
