Titans have a new subclass in Destiny: The Taken King called Sunbreaker, and it can be a whole lot of fun to play. Especially if you're using the "Explosive Pyre" perk, which is described thusly:
Enemies felled by your hammer explode, chaining fiery Solar damage to others.
It's a fun perk to use in crowds, but the video above is a bit ridiculous. The enemies spawn in just about the perfect pattern for the damage to continue, and soon the ground is littered with engrams and glimmer. If you want to farm, well ... this may be a pretty decent way to do it.
I think my favorite part is when the Guardian in question just sits down to watch everything in front of them die a flaming death.
We're not saying Explosive Pyre needs to be nerfed, but this is one of those fun videos that shows what happens when players use these abilities at just the right time. Maybe wear some shades while watching.
