Increases blaze damage

Well, yeah. My friend and I tried this in MA, where after the initial blow of Blaze he support shots. Instead of dealing ~21k, I dealt 42k with his support shot, rank 1 and mastered. It wasn't a critical hit either. I'll test this more later. Still pretty new to this so I'm just kinda posting stuff I found over my years playing lol.

This has been known for a while. Support Shot does indeed influence the explosive damage dealt by Blaze. An interesting question with an unknown answer at present is whether or not Rage Impact influences in kind.

Both hits of Blaze are considered both magic and melee damage. Support Shot increases any melee damage done, so it'll work for Blaze too. Was this not written on either of their pages? It probably should be added.
