Steve,
In the write up for Freon in the VIPER sourcebook (which totally rocks, by the way!) he has an invisibility power that is given a -1 limitation, "only when not moving" (or something similar).
However, if I look under the power description in FRED, or the limitations matrix in Hero Designer II (again, great job!), the Chameleon limitation is only worth -1/2.
Not trying to be a number-cruncher or a wise guy, but I'm trying to understand the difference between these two limitations that justifies the additional -1/2 limitation? I only ask because I was taking HD2 for a test drive last night, and decided to input Freon as a test. I didn't understand why I just couldn't choose Chameleon, until I saw the difference in limitation values.
Thanks for all that you and the Hero Games staffers do! You've collectively revived one of my fondest childhood pasttimes, and that's a joyous thing!
