Pyroblast

Description
A fireball that deals 50 damage on contact, and explodes after a brief delay, dealing an additional 100 damage in a 3x3 area.

Strategy and Synergy
Pyroblast is a well-rounded damage-dealing spell that is highly flexible and can be taken in many decks. At a total of 150 damage on the primary target, its damage output is cost-efficient and highly effective in many circumstances, whether against one or multiple enemies. The non-negligible AoE damage that this spell possess also offers a great control over large groups of enemies and/or obstacles.

Unlike many other area-of-effect damage-dealing alternatives, accuracy is still an important factor when using this spell. This is due to Pyroblast's AoE being completely dependent on the location of the target hit and therefore gives the player much less control on where they would want the shot to land - the spell would have no effect at all if the initial shot missed!

By virtue of being a simple 2-cost spell with no effects other than simply dealing damage, and  are naturally good upgrades to have on this spell.
