Refresher on DRK from 60-80

[Mekhana]

DRK guide for boomers:

0-69
Pull trash until the dungeon forces you to stop or the healer has a mental breakdown
Keep darkside up
Unleash 3 or more enemies. Quietus over bloodspiller as well.
A full mp/job gauge bar are wasted. Spend your resources.
Pop a mitigation for each trash pull. Don't rely on Dark Mind for most trash. Use Reprisal and/or Arm's Lenght as a secondary minor mitigation. For bosses, you can use the first to reduced party-wide dmg. For very large pulls Abyssal drain may heal you from anywhere to 25-50% so use it.
70+
Practically the same.
Save 3k MP for TBN. TBN single-handedly can replace one mitigation in many scenarios on its own unless dealing with a constant, very high source of damage, such as pulling half the dungeon to boss from. Use it on top of a Shadow wall or rampart so the sprout healer becomes confused from your apparent godlike invuln.
Even if the bubble doesn't pop the less the healer requires to heal you, the more the healer can dps and the more of a chad you look and feel. Do this unless fighting very few trash enemies. Practically anything your Bloodspiller is enough to keep you alive.
For either Blood Weapon on Delirium can both be popped on cooldown as long there's something to kill unless there's a large pull right after.

For dungeons its fine to finish the Unleash combo with Stalwart Soul on two even one enemies sometimes to get that quick 20 gauge. Just don't do it again unless they are milliseconds from dying and it doesn't matter.

Only pop Living Shadow on packs or bosses.

Only pop living dead if you are literally about to die.

Its a dungeon if you don't mess up someone else will. Take it easy mah dude and have fun. Enjoy your 2-3 commends per run.
