Do the Enlarge Spell penalties mean the damage can become negative?
Benefit: Before using a wizard at-will or encounter attack power, you can choose to take a -2 penalty to each die of damage rolled with the power to increase the size of its blast or its burst by 1.
So for example, on a 2D6 + Int mod.
damage spell, with a roll of two 1's ... is the damage Int - 2, i.e. Int + (1 -2) + (1 - 2), or just Int + 2, i.e. the minimum on a D6 is 1 ?
