- When Kholer lifts his hand and glows, he is casting Shield Stance. Shortly after his Shield Stance ends he will pull everyone nearby to him by using a special Dagger Storm. Every pulled player will be stunned and Kholer will begin a whirling attack, generally meaning death.
- The dagger - and therefore, the pulling effect - can be dodged with rolls and blocked by Aegis. Guardian's Virtue of Courage and "Retreat!" may come in handy. It's also a projectile, and can be blocked or reflected with skills such as Smoke Screen or Feedback. Additionally, skills which give Stability can prevent players from being pulled in to their death, but need to be activated right after the glowing animation
Basically, Kholer gives an animation so you know when he's about to pull you in. What the wiki doesn;t tell you is that his pull is actually 3 scorpion wires that fly out to people nearby. This counts as a projectile so it can be dodged and blocked. You need to keep your eyes on him and when you see the animations described above you dodge. It's simple once you get a rhythm going.
I have noticed that animations in GW2 aren't always as obvious. I have played many action games where dodging and timing are key. Heck just go play Zelda and the mechanics in boss fights are the same, however there is something about GW2 that just seemed to be a little harder to get the hang of. I can only really put it down to bad design or programming. It's literally the only one where I couldn't seem to figure out HOW people were getting so good at dodging when I seemed to get hit by everything. Eventually it all just clicks though and you get good at it.
Make sure you start experimenting with skills you have always overlooked as well. I was pretty static with my skills during leveling but I'm way more willing to change skills and traits on the fly now. I change them nonstop in dungeons to fit the situation.
I would recommend valkyrie armor as well. Keep your zerker trinkets etc, but change the armor to valkyrie for extra health. Also, what traits are you using?
