Power at a Price

I first wanted to create the dark hearts using manufractured heartstones make the for balance ending , but the for balance purity option is much more appealing and easier

 

If this is a side quest, should there be game changing factors like all npcs hating you? Otherwise, this is a great idea!

 

there should be some great cost because it would b the strongest weapon though ppl would only care thats worlds are dieing if they live/going to live on it

 

The cost is npcs hiding or attacking you because you become a villain .

 

or i could be somthing like infamous some fear you some luv you (love is misspelled intentionally)

 

This is a really awesome side quest story line, though I find the dark heart to be a bit over powered.

 

It is to be an endgame item with one of the longest cooldown times (if they are going down that path)

 

As the thread name implies, the power does come with a price, so you get op weapon while having an enemy chase you or having people hate you.

 

Absolutely and Fantastically Brilliant, sir!
You should make your own game!
this would be an interesting addition, in game content, or mod.
indeed, sir! indeed!
