Yesterday I was playing around with the DDI character cuilder and found the Avalanche Hurler DDI paragon path for Rangers, so I decided to see what I could do with a ridiculously huge thrown weapon.
Of course, to my dismay, I can't simply increase a d12 to a d20. It would have been hilarious, but that's not how weapon dice sizes work (the progression is d12 → 2d6 → 2d8 → 2d10).
Taking a 2d6 weapon (gougeDDI), making it thrown (Hungry SpearDDI), and using the Avalanche Hurler PP gives me a 2d8 weapon. Is there any way to increase the weapon dice again to reach 2d10, even on a temporary basis?
