The majority of paladin's job actions function incorrectly. The affected actions appear to be replicating the effects of certain gunbreaker actions, rather than functioning as intended. This bug has been consistently occurring since patch 6.3, so for safety purposes, I recommend reverting the job to its patch 6.21 iteration.

The Paladin abilities and the respective gunbreaker abilities triggered are provided in a list below for the purpose of fully cataloguing this error, sorted by level of acquisition.
Fight or Flight - No Mercy
Sheltron - Heart of Stone
Prominence - Demon Slaughter
Goring Blade - Double Down
Royal Authority - Solid Barrel
