trade in Hellstone Bars with Demonite.
OH stuff monday WHAT THE forget ARE YOU DOING.
Hellstone Bars are way more useful than Demonite.
also loving Fire Imps are the worst enemies in the game. They are unfair to the point of frustration. I can understand them being stronger than the run of the mill zombies or skeletons, but they've just got too much going for them that makes an unfun enemy.
