I’m terrible with the names of the functions but my favorite combo was the bounce shot augmented with the corruption and the starting ability. It meant that my shots bounced to all targets, caused them to slowly decay and also stun locked them. I combined it with cloak as a passive, which meant every time an enemy died I went invisible. Most fights I could fire off a few shots and then just run away. Not the most honorable tactic but really effective.
Yeah, this is the cool thing I really like about this game. Messing with combos to come up with interesting was to fight.
