Did a little trap/mine reading and briefly entertained the idea (before I did the reading) of a ballista tossing mines... But of course it doesn't work that way - one mine spawns a trap that spawns a ballista. Then I was looking at the list of traps and noticed fire trap of blasting, and remembered the joke about Pohx's RF build really being a Fire Trap build in disguise, looked at his build and noticed that he's back to 6 linking RF instead of the advanced build being 6 link fire trap + 4 link RF. Looked into FToB, and it scales based on the target's current burning damage, which is inflicted by RF... Welp, looks like I am going to sit down with Path of Building and see what I can come up with when I get home. Maybe mines, maybe RF, maybe three FToB in a trenchcoat pretending to be a RF build.
