Translations:Task System/5/en
From BlackTalon Wiki
After accepting a task on whichever difficulty that you chose, you can now head to the spawn and start killing monsters. Do not be afraid to party up, since you can share a task progression with three other people, as long as everyone deals at least 1% of the creatures HP as damage. After finishing, just return to the same NPC you got the task and turn it in. And also elite monsters will provide extra kills towards the progression.
