An example of using Ivara and Pennant Heavy Attack build against a Steel Path Acolyte.
Apparently Heavy Attacks with some weapons (I'm certain about Hate and Pennant) have a forced Slash proc. The Slash proc-caused DoT scales off initial damage and ignores armor.
Granted, the Acolyte got shot several times by the Corpus mobs, but I'm pretty sure it was one of bleeds I inflicted that did them in. Otherwise IDT the affinity numbers would show up.
