Use pyre ring to convert the damage of the initial hit to fire, orb of storms with curse on hit (flammability temp chains imo) to proc your EE & mastermind of discord, link with chance to ignite + fire pen + ctrl dest + inc aoe. For single target a 4L pizza with conc efect, pen & chance to ignite.
Basically you won't do enough dmg if you build it for the degen since it doesn't scale as good as ignites.
