Ember Fire Blast and Rhino's Charge don't hit all enemies on their path.

To test that Rhino's Charge not hitting all enemies simply use Ironclad Charge augment + smth like Larva. You will always get random results.

With Fire Blast a bit different problem - if you cast it in air everything fine and hit all enemies in range, but if on land - it sometimes simply don't hit enemies in a cone behind closest to center target damaged target.
