Hemorrhage (boss killer)

The Stack Build

This guide focuses on exploiting the synergy for high damage over time (DoT), especially against bosses.

Ball Combinations:
x , x or x (Fast stacks), or x (Whole map application)
The Final Ball:
Since you cannot remove the ball from , I highly suggest x Curse.

Why This Strategy Works
I choose because he throws two Special Balls, immediately creating more stacks. Adding doubles this number, resulting in a total of four special balls. ' ability is that your balls deal less damage, but this drawback is irrelevant since our main damage comes from , which deals 20% of the enemy's current health as damage. Because you're stacking so much , 's effect ticks constantly.

Performance
This build may not be as good as x for instantly clearing a whole horde, but it deals continuous damage through ticks. You can kill trash mobs quickly, though not as fast as dedicated Area of Effect (AOE) builds. The build truly shines against bosses. Bosses often die almost instantly after they appear.

Essential Tip:
For the Boneyard stage, I suggest getting the passive for the before the final boss fight, as you can only damage it via its crown. While passives aren't strictly required for this build, I highly recommend using so that your balls can go through enemies which provides stack around the map. I also included the so that you can exploit the EXP gem and gain levels to easily max the balls needed for this build.
