Does Flumefire Rage work with Blasts?

[Cryypter]

The feat Flumefire Rage from the Elemental Master’s Handbook increases the damage of fire evocation spells. It also lists the kineticist's Elemental Focus class feature as a prerequisite, and mentions blasts in the part detailing the Fort save DC, but as far as I can tell, using a kinetic blast does not count as casting an evocation spell.

Was this feat intended to work with blasts, and if so, is it a typo/oversight, or is there something I am missing?

I think it's an oversight. It needs an FAQ/Errata, but until Paizo reprints in a hardback book we are out of luck.

I suppose there is a small chance they were referring to the Elemental Focus ability of the arcanist archetype, Elemental Master. It does make some sense they were reading it, because the book is Elemental Master's handbook, so you may as well throw in a feat for the Elemental Master archetype.
