Casting Time 1 standard action
Components V, S, DF
Range medium (100 ft. + 10 ft./level)
Area cylinder (10-ft. radius, 40-ft. high)
Saving Throw Reflex half; Spell Resistance yes
A flame strike evokes a vertical column of divine fire. The spell deals 1d6 points of damage per caster level (maximum 15d6). Half the damage is fire damage, but the other half results directly from divine power and is therefore not subject to being reduced by resistance to fire-based attacks.
By the way…
This spell does not start fires on a ship unless the ship rolls a natural 1 on its saving throw against fire damage.
