Re: The Ten Things I Love About 6e and the Ten Things I hate about 6e
You can easily adapt costs for your own game. Many groups do not have a problem with it.
So, if the attack did 35 STUN before, you can quickly figure out that each 1.5x did an extra 18 STUN, so take 35, take an extra 18, another extra 18, and yet another 18.
Using the philosophy that if there are two ways to build an effect, the more expensive one is likely the correct way, just declare that any construct with the Usable As Movement Advantage must use the most expensive form of movement as its base. Just like you probably wouldn't want to allow +40 Leaping, Usable as Running, since it's far cheaper than actually buying that much running straight. An advantage should generally not make a power (+40 Running) cheaper than buying it without.
With DCV as its own CHA now, you could easily buy +12 DCV; Costs END for 40 points. If you assume that Shrinking also includes some drawbacks like Extra KB, that could explain it. Or else just take the whole Size Template and put a Costs END on it.
But Blast is just one power, and you'd have to buy PD and ED separately to defend against each type. How is Flash different?
Only if you can attack through the Barrier, right? Which is an Advantage either on the Barrier (Transparent) or your attack (Indirect). So instead of 43 BODY for your 20m Barrier, you end up with 23 for a One-Way Transparent Barrier to a single type of attack.
