Gorefiends will sprint once they are shot. They do not sprint on sight despite having 100% sprint chance. Gorefiends will only begin sprinting upon getting close (8m) to players. Gorefiends move slowly when docile, and sprint when enraged. Damaging with on-perk weapons and then finishing it off with an off-perk weapon divides the XP and grants it to both perks.Killing with weapons other than your current perk grants the XP to the perk that weapons belongs to.
