Rathbreaker Raging Spirits & Ember Fusillade

During the Rathbreaker fight both my Raging Spirits minions and my Ember Fusillade are targeting the hyenataurs on top of the ridge. this compounding with the fact that fusillade changes aim direction off of my mouse during dodge is quite frustrating since about 70% of my damage is going to waste on invulnerable enemies not even in the arena due to a mix of me being bad (The fusillade dodge thing is likely intended so I am trying not to be too frustrated by it) and enemies that are hitting me with projectiles that won't die to auto aiming attacks.

So all my single target damage is focusing on enemies that are invulnerable and outside the combat area. This is really frustrating

Should probably do a better breakdown

Steps
-Initiate Rathbreaker
-Use Spells Ember Fusillade and Raging Spirits
-Raging spirits from any fire spell if spawned close enough to back wall will fly up the ridge to attack invisible enemies and the hyenataurs
-Ember fusillade will sometimes fly away from Rathbreaker and aim for enemies on ridge, this seems to be proximity to back wall after several deaths
