Burning entangle: Evocation. All other entangle spells seem to be transmutation (in the druid's spellbook anyway).

"This spell functions as per entangle, except it sets the foliage on fire. A creature that begins its turn entangled by the spell takes 4d6 points of fire damage (Reflex half), and a creature that begins its turn in the area but is not entangled takes 2d6 points of fire damage (Reflex negates)."

Does that mean that the part that "functions as per entangle" requires a transmutation Reflex DC, followed by a Fire dmg Reflex DC on the creature's turn? Or is the whole thing evocation?

You've guessed it, my druid has greater spell focus in Transmutation.

Thanks!
