Boule de feu

Fireball YXR Sorcery Text(5th+errata): ~this~ deals X damage divided evenly, rounded down, among Y plus one target creatures and/or players. [Oracle 2000/02/01] The Y in the mana cost works the same as X normally does. [D'Angelo 2000/03/03] If the damage to creatures is redirected to the player (via Jade Monolith or other effect), the damage from the Fireball can all be prevented with one use of a Circle of Protection. The trick is that all damage from one use of a spell/ability can be prevented at once. [WotC Rules Team 1996/10/03] The mana spent for extra targets is part of the mana cost. [D'Angelo 2000/03/03]

Fireball Sorcery Fireball deals X damage divided evenly, rounded down, among any number of target creatures and/or players. As an additional cost to play Fireball, pay for each target beyond the first.
