Has this not been thought of at all?
Perhaps its the crafter mentality...
It seemed almost like simple math to hope that ones super crafted weapon would bend an eye of the soul engine's story generator and 'test' the yielder in ways the would make epics weep tears of manic goo...
After reading up on crafting, my thought process has even evolved to wonder how 'custom' my research into swordsmithery can be bend.
Will I have to follow an algorithm to trigger the game to give me the 'you discovered..." gimmick, or can I literally mash an ass ton of metal ingots together, create an 8 foot long blade made of a metal from a fallen star, strap a handle made from the heart of dryad's tree, wrapped with the leather of dragon hide and finally add a pommel made of a finely smooth sphere of ruby that acted as an eye for some crude golem a hero slew a few days back?
Id name that weapon. and then Id give it to someone out of fear that 'fate' would see it made and desire to test me, the humble crafter.
Would I then need to seal it away in fear of danger being 'called' to the weapon if no hero was brave enough to take it on?
I hope so.
I would make this my soul purpose in gaming to make sure I could create an item so incredible that is mere existence called the might of the soul engine's power.
I'd also get to meaningfully say (Witht he game's own mechanics making it true) "It will ensure only the worthy carry it. It knows...it wants to be used."
