well...... i ...i like the idea of making smithing harder... and i like the potion idea aswell..
but i dont agree with ya with the materials needed for the spells , unless the materials would
be need to make some magical equipment...like +1 , +2 ,+3 platemails ans such..
1.) about the smithing.
GREAT! i love the idea!
but the all the prices should rise tooooo....... and really RISE not just 2-3 gps more like 20 -30 gps and ya would make em harder to do...then i would be more medieval platemail thatn now.
now i dont care for losing even 20 platemails , heck im so rich that i can give em away for nothing (Not that i would give YOU anything

)
if it would be something like this.. then i would rock
dagger , 1-2 bar (different types of daggers)
short sword , 2-3 bars
swords 3-5 bars ( different types of swords) (this excludes firesword)
shileds 2-8 bars ( different types of shileds)
viking helmets 1-5 bars
full helmets 4-8 bars
axes & warhammers 3-6 bars
producting items 1-4 bars (scythes , needles and such)
knigth boots 5 bars
metal gauntlets 5-6 bars (are they called "metal gauntles" , i cant remember?)
useless stuff 1-3 bars ( horns and such)
firesword 9 bars
platemail 12-15 bars (truly hard and expensive to make , so profitable if they would pay for ya
in shop 30-40 gps...
chainmail 8-9 bars ( quite hard ...but not as hard as platemail)
2.) the bottle idea is good... so ppl should have to really MAKE their bottles and potions..
3.) (my own idea) if there would be some new magic area for making magic items..
there would be two persons needed , high level smith and high level mage ...if they would find some rare materials ( some could be used only by the smith and some only by the mage/druid)
they could unite their powers and make some + something stuff....ofcourse the higher smith and mage/druid the better items could be made...
well what do u think?
sorry about my bad english
