Burst of beams
What changes
The main attack remains an arcing Haemolacria projectile. Its landing burst sends beams outward instead of ordinary split tears.
How to approach the setup
Aim the landing point into a group. Watch the arc as well as the enemies so you can keep moving while it travels.
A practical suggestion for this pair. Check the rest of your inventory and the room before relying on it.
The caution to remember
Azazel and Tainted Azazel's inherited beam is overridden by Haemolacria and does not supply this special burst by itself. The actual Brimstone item is the ingredient here.
What this teaches about a run
Two powerful weapons may combine through the projectile's landing effect, rather than firing both attacks directly.
