I'm not seeing how it can go either way. Both of your sentences are saying the same thing. That the only target of a Ranged Attack can be Non-Adjacent opponents.

It's not the Colossal Rules that you need to look at, wholly, but in part you need to take into account the wording of PW. PW states it doesn't target, so you're not breaking that rule of targeting Adjacent foes.

Take EE, if the Colossal Targets and opposing figure two squares away and there is another opposing figure adjacent to both the Colossal and the target of the attack that Adjacent foe will also be dealt damage, Due to the nature of Energy Explosion, not due to what the Colossal is.

When you see this, then you'll see that they can use PW while adjacent with another non adjacent foe. And that PW will damage all figs within range.

I think everyone in the thread has come to an agreement that:
1. A Colossal character can use Pulse Wave if there are adjacent opposing characters if there is also a non-adjacent opposing character within range.
2: If a colossal character uses Pulse Wave all characters within range, adjacent and non-adjacent, will be affected.

The question still out is if Colossal characters can use Pulse Wave when there are only adjacent opposing characters.

I say no for the reasons I've stated in earlier posts, but there are a lot of people who have posted that feel differently. Their arguments have merit. That is why it would be good to have an official ruling.

So, you're saying it's a known fact that there are no known facts? : - )

Well, basic math is universal, so we just need to start expressing things in binary, right?

Edit: Sorry, I meant 010011100110111100100001

I've said no as well, case in point of my last post. The only reason they can when a Non-Adjacent figure is withing range is duo to the rule for Colossals.

And this question has now been answered. A colossal character cannot use Pulse Wave if all the opposing characters that would be in range of the Pulse Wave are adjacent to the colossal character.
