Chmm ... if I only had online source of Tinker & Goblin revised rules. I hope they improved tech rules ... since only thing that is limiting Groog now is lack of gold. And I'm speaking about things that he can build
now Gatling Gun anyone ? Chainsaw, Eletrically Charged Axe for Snarrek is quite avaible too.
So should we update our Chars DM ? For now I can change names of stats to more apporiate. But will need guidance about changes in Tinker class.
And one more thing DM, I want to warn You that as soon as Groog will get chance he will scavenge/build Goblin Shredder and play Steamwarrior !
