Movement speed is randomized within ± 10% range and further modified by a multiplier based on difficulty. Once enraged, Gorefasts will never stop sprinting until they are killed.
Gorefasts will sprint once they are shot. They do not sprint on sight despite having 100% sprint chance. Gorefasts will only begin sprinting upon getting close (8m) to players. Gorefasts move slowly when docile, and sprint when enraged.
The base damage value further modified by the difficulty-specific multipliers. For kill reward calculations read Dosh Mechanics.
