Swordsage with Resounding Thunder and Thundering Weapon

[Danceofmasks]

Yeah, so it doesn't work with the swordmage's at-will.
If there is a weapon that grants thunder keyword, Resounding Thunder will work just fine with them Fighter or Rogue or Ranger powers.

Now, because of the existence of the feat, such a weapon is unlikely to be printed.
It would be more busted than team frosty.

Storm Gauntlets in the Adventurer's Vault on page 136 would let this trick work! The Power is Daily but lasts until the End of your Next Turn so it could Improve a lot of Attacks!

It only works on melee attacks, though. The feat only works on blasts & bursts. Methinks the twain do not meet.
