The ingame descriptions of powers should be treated as the vague ramblings of a madman rather than canon on how the powers stack up. They're frequently wrong, out of date or both.
The newly updated offical website unfortunately took the ingame descriptions so its equally unreliable and error-strewn.
Best sources of info are Hero Builders or the living brains of people like MaX.
Thanks for the info. It's a bit annoying to pick a power and then find it doesn't do what it's supposed too. Mind you, as it stuns you can then snipe them again anyway, so silver lining and all that. 
I'll be sure to check out Hero Builder, thanks again.
Cosmic Burst IS the silver lining from Rad, love attack, just like Bitter Ice Blast but with a harsh secondry effect
"Well, they found my diary today.
They were appropriately appalled
at the discovery of the eight victims
They're now putting it all together.
Women wrapped in silk
with one leg missing
Eight legs, one body, silk,
spider, brilliant!"
as stated pay NO heed to the ingame 'superior' descriptions as they are farcical to say the least, why they dont give us figures is anyones guess but fortunately the herobuilders are pretty good.

Its your fault

What is Extreme damage in Rad Blast, is Superior in Ice Blast. X-ray beam deals as much damage as Ice Bolt but is listed as "Moderate," so they are in-powerset-type of listings.
But don't trust them blindly, Ice Storm is listed as "low" damage but it does infact more damage than BIB!
Hi all.
Wasn't quite sure where to post this, as it's a technical issue, but only corruptors could confirm it or not I suppose.
Anyway, i've noticed that Cosmic Burst does less damage than Proton Volley, despite Cosmic Burst being listed as extreme damage and Proton Volley listed as superior. Both powers are slotted identically, double acc single dmg, and when tested out against Longbow the Cosmic Burst does about 15 points of damage less than Proton Volley.
So it seems that either the damage code listings are incorrect or one of the powers is doing more/less damage than it should be. Any thoughts?
