In last session, out of panic, my magus used an empowered mirror image to protect himself. I rolled a 4 on the dice, +3 since I'm level 9, which totals 7 images, and the empower would bring that number to 10.
However the spell specifies a maximum of 8 images. Does such limit get "empowered" too, going up to 12 in this case?
Based on a discussion in the Paizo forums about this, I get there are two main point of view:
The first one states that the 1.5 multiplier from empowered spell applies to the whole expression
min(1D4 + 1/3L, 8), giving a total of
1.5 * min(1D4 + 1/3L, 8), effectively going above the limit.
The second one instead is based on the interpretation that the formula should be
min(1.5 * (1D4 + 1/3L), 8), applying the multiplier only to the actual "variables".
While as a player I most certainly like the first interpretation more, is there any kind of "official" ruling on this, or is it DM choice?
