there are many weapons in the Obelisk War prize shop ... and I don't have lots of points ... and I want some of the wearables as well ... so which weapon should i get ?? is the Shovel a good weapon ?

Last I heard, the Shovel was glitched, and wasn't working properly, so we haven't been able to figure out if it's really worth the prize points. (it could be that the stats we do have on it are just what there is, and it really is that underwhelming, ahaha.)

The other weapons though, are in the Battlepedia. http://www.tdnforums.com/index.php?/topic/37732-obelisk-war-prizes/

I think that some of them still require some testing, but the preliminary stats on them are there. :D
