Channeled Fireball (3.5e Spell)

The bread and butter of evokers, the fireball was severely lacking in flexibility. Therefore, some smart evoker made a version that was weaker at first but could be channeled and made weaker or deadlier depending on the situation. The channeled fireball does 2d6 fire damages to the creature it targets. You may only cast Channeled Fireball once per round.

Channel: A channeled fireball can be channeled in the following ways.
 * Lesser: Change the spell subject to a 20 ft. area.
 * Lesser: Halves resistance to fire against the fireball. The fireball deals +2 damage per d6.
 * Greater: Increase damage to 1d6/level.
 * Greater: Does not expend the spell slot used to prepare the spell/spell per day. Only apply if the channeled fireball is cast with a 3rd level spell-slot/spell per day.
