So I have been trying to take care of a quest (I don't remember the name of it) where you have to rescue an NPC from Fort Nikiou where he is being held by the firebrand. Most npc's in this fort are in their mid to late teens (15-18) and my character is level 30. Now the problem is this, there is a Captain that I need to kill who is level 17. I have tried everything I can think of to kill this guy and nothing works. I have poisoned him, tried shooting him in the head with arrows, hit him repeatedly with heavy attacks with a poison blade, and I just can't seem to do significant damage to him,.
I know that part of it is that there are always a ton of other npc's around when I attack him so they all join in the fight and I get overwhelmed pretty quick, but I have been able to devote enough time to him that any other npc of his level would have been long dead. I just don't understand it (I have managed to finish the quest without killing him btw). So any suggestions/ideas would be appreciated.
Have you tried using the crossbows that are scattered around certain camps? I'm not sure which specific camp you are in, but there are always some of those crossbows that are attached to the ground, and they are very powerful. I would try to the tactic of stealth killing most other npcs in the camp, then lure the captain to where you can use the crossbow, and voila!
