Quality goes up to 3000 in very rare cases it seems. I have now had 2888% a while now, and even though I spent about 10k gems and have almost doubled my blacksmith I have not gotten a better one. What would fix this is a removal of the blacksmith skill cap. THis will allow for slightly faster progression on the later levels of hellstone.
What does annoy me is when I get a pickaxe of 2800% or so, and then see no real improvement for ages. My blacksmith is 1,5x stronger then when I last got a pickaxe, but I cant get lucky enough to beat 2800%. Love this game tho.
Tip for the hard badge: only upgrade the hero, mage tower and warriors. Only use warriors and mages in the levels. Put a mage at the beginning of each level, and at the very end. Add a warrior next to those mages, and make mages inbetween. Use the heroes to take down monsters, be wary of golems since you do not have cannons, but the hero takes them down in seconds. Trojan horses are very weak against warriors, so are most bosses, as they take time (slow down) to kill them.
Excellent game. Favorited last week, came back because of updates the developer keeps making. It is good to have a developer that listens to his fans. Changed my rating from a 4 to a 5 because of that.
Just some advice, dont try to get the impossible badge using the arrow keys, use your mouse instead. Also, save up your special, and use it when you are in trouble, using 9 missiles this will lagg the game pretty much, allowing you to dodge the bullets in slow mo
It'd be pretty embarassing if we didn't, no?
