since I still see a lot of people having problems with the heat room in the Thaumanova Reactor Fractal, I tought I will record some videos the way I do it.
Unfortunately, I was only able to do it with 6 classes. I could't find a way to do it on Ranger, Guardian and Revenant. However, I think, that it would be possible to solo it on Dragonhunter aswell, if your race is Norn. Mine isn't though, so I could't try that out.
Here are the clips of all the other 6 classes:
You can find details about skills in the video descriptions.
Edit: Thanks to /u/PoorYarga for delivering a Druid, /u/Randommuser for delivering a Herald guide and /u/joaobigger for the Dragonhunter one.
