- Onslaught of Shadows' flee will only be applied to enemies near Hecarim when he finishes his charge. It is not applied to enemies that are only hit by the riders. This is not conversely true - enemies who are feared by Hecarim will always receive the damage as well.
- Onslaught of Shadows' flee is distinct from the usual fear in that affected units will always travel away from Hecarim for its duration, and it has a different Loss of Control Indicator icon to show this. The flee is dynamic, meaning that the affected target will continue running away from Hecarim, even as he continues to move himself, allowing some degree of control over where affected units will run.
