Arbalest's Accelerant is omni-elemental which is awesome, but the triggering factor, Oil Chain, is locked entirely into being fire damage. This is... counter-intuitive, and prevents the class from being truly coherent in terms of elemental specialization for anything other than fire.

It doesn't seem unfeasible for this to change.

Functionally (please correct me if I'm wrong) the fire tiles left by Oil Chain are identical to Cinder tiles. Why not ditch the flames for Cinders, then add elemental impact functionality? Ice sheets, Air Shafts for wind, Static Fields for lightning, with poor earth left with a tossup between rocks and flowers.

Alternatively, simply have Accelerant and Oil Chain share the same criteria for typing, keeping the flames and maybe making their colouration obvious as to what element they'll deal.
