Flaming Crasher

Uh oh
Upon play, roll a 8-sided die. The damage is the number face-up, divided by 2 (rounded down), and can be directed to any creature or planeswalker (excluding the player).
{2}{b/r}{b/r} - why is it on fire
If the player pays the extra cost, roll 2 6-sided dice in conjunction with the first 8-sided die.
