The Collector continued to chase the fighter as he scaled down the verticals slope of the mountain with rapid grace.
The fighter disappeared into the foggy depths below, his extreme speed parting out a puff of fog as he entered the thick veil of white. This was likely to limit the Collector's range of vision and therefore its ranged combat capabilities.
No matter, however.
The fighter's kinetic-muscular vision was dependent on establishing a clear line of sight, and in this fog, that would be limited, though the Collector did estimate that a fighter of such a caliber would not be entirely crippled by this fog either.
Regardless, the Collector had an advantage in a direct melee confrontation because it did not need sight, for it was capable of relying on its sensitive hairs adaptation to compensate more than adequately enough.
