I am using sunshot along with the sol invictus aspect on my sunbreaker subclass. Prior to TFS release, this combination was consistently creating sunspots as described in the description for sol invictus (defeating scorched targets creates a sunspot). However, since TFS, I have noticed that sol invictus rarely ever works with sunshot if ever. I am aware sunshot splash damage was nerfed 10% but that should not result in it making sunspots 0% of the time. I also know that the sunshot is indeed applying scorch stacks (hard to tell as the sunshot also highlights targets) as I am also running the ember of searing fragment and I am still consistently making firesprites which tells me it is still applying scorch but for some reason, sol invictus no longer works with sunshot.
