As someone who actually bothered to kill the first boss and carried on, I have to say that the biggest flaw of this game is that the third boss seems to be completely unkillable... It's almost as if the creator knew that people wouldn't bother going past the first two bosses, so didn't bother coding the third very well. Very sub-par game overall, but good art and a good basis. Programming and the difficulty of the first boss compared to the rest of the content makes it very hard to give it anything more than 2 stars. Very disappointing.
Architect: To build my flowerbed, we will need 500 logs, 500 stones and 500 lumps of copper.
Me: What kind of flower bed needs that kind of resources?!
Architect: Are you questioning my process? Please tell me you aren't questioning my process.
Me: I just think that the resources could used in a much more effective ...
Architect: DO NOT QUESTION MY PROCESS!!
Should also mention that block caps out at 90, not 100. Any point you spend over the 90 threshold will take away any block you've gained from Smeel of Powder spell if you reset.
People seem to be confused about the whole % drops thing. What it means is that there is an implicit chance that each mob drops certain types of material (for info on what monster drops what look at digitelanimefan's post). This increased % drops means that mobs are more LIKELY to drop items. Once you have enough, you get drops from almost all mobs.
