Public perception is that Karka are hard to kill. So hard that people in my guild have stated, “I’d rather have my gums scraped than fight karka in Southsun”. The truth, however, is that karka are fun, easy and profitable to fight. You can make more than 3gp+ an hour from Potent Blood, Powerful Blood and Karka Shells. All it takes is a coordinated group with the right set of skills.
What people find brutally difficult about the Karka is their ranged Spit attack. It can kill an unprepared player. It can also be reflected and be used to knock 50% or more of the life off the Karka with an ability that reflects projectiles. The Guardian, Engineer, Ranger and Elementalist all have an ability that can be used to reflect projectiles. The Mesmer, however, doesn’t have just one, she has seven.
Here’s an example of the Engineer’s reflect ability:
And with a Mesmer:
The last video shows just how poorly my mesmer buddy and I fought (we are out of practice!) but still managed to slaughter 7 Karka at the same time!
Prior to the last patch, the Phantsmal Warden was the most powerful mesmer reflector. It is capable of reflecting an number of Karka attacks and nearly killing all of them. Since the latest patch, iWardens have a small delay from when the start protecting and can be killed by an angry karka before spittng. Feedback has since become the mesmer reflector of choice. Simply aggro a group of Karka, cast the Feedback in your own area and watch as the Karka murder themselves. The trait Warden’s Feedback allows all focus abilities to reflect. There’s a huge arsenal for the Mesmer to reflect and farm.
