It seems that , in order to do the quest, player must have 8 lvls in Trapper talent. Unecessary waste of skill points can be avoided by unlearning all skills and attributes via Soulpatcher, though, this would require money.
Note: You don't have to kill the enemies with the traps provided. You only have to one hit kill the enemies. I used a level 10 block breaker and completed the test without any trapper skill.
