Original:
Should deal fire and electric and stun. Or maybe just 2 of those. Or even just fire or stun. But thats just my opinion.
Then it might be worth something, because at the moment, its more of a Mildly Temper'd version of nitronome.
EDIT:
Most people agree on BAB getting-
-Stun status
-Larger radius
-More damage
Most people agree on irontech getting-
-Less walk debuff
-Shorter fuse
Ideas that seem plausable for Deconstructor-
-Deconstructor upgrades from super blast bomb; is 4*, while Heavy deconstructor would be 5*
-Shock (or some other bonus) against construct
I'd rather they remove the negative speed on it... But this isn't a bad idea either.
