Hello Atholl here with a new idea about the catalyzer and how it would work.
It's just a rework of the charged shot, enjoy.
1) When an enemy affected by charged shot dies the orbs orbitating around it instead of desapearing will explode.
or/and
2) charged shoots upon activation acts as normal shots , let me explain , they are the same as now but with the explosion they can activate other charged shots on the enemies in the radius.
or/and
3) When the duration expires the orbitating orb explodes
these changes are made to create an easier way to use the catalyzer in crowds or against enemies hit with the carged shoot but not by the normal shoot, it will also make it's way in the LD meaning that when you hit someone with the charge you don't have to hit it again with the normal.
When a "tagged" enemy is hit with the normal shot, the charges are detonated, but then become regular shots and move outward like normal shots? You could use it to set off a massive chain reaction, and it would increase potential damage to a group of tightly packed enemies.
