Say I perplex Nightcrawler's (or any 0 range HSS piece's) range +3, with replace then modify his range would still be 3, correct (half of 0 is 0 + 3=3 range)?

that would be correct.

Hmm... never thought of that...

So if you had a HSS figure with 10 range, and perplexed it up by 2, then he'd HSS (cutting his range to 5) and still have a 7-square reach?

Absolutely!

Yep, which I thought was the case, I just wanted to confirm it. We were having the discussion at tonight's game.

this is because you replace, then modify

"Replace, then modify..."

Kii-yah! (ninja'd)

This helps CA Quasar's range when using his special power too. You could get a 7 or 8 pretty easily out of him after he phases five squares. And what I realized is nice, unlike running shot, you can carry a friendly figure (SHIELD TA guy to boost his range) and it won't affect how far he can move in order to use the power.
