How is SoZ's crafting system a mess? There's personal preference and all, but I find it to be much simpler than the other OCs.
Well, the basic idea is quite nice, but the way it was implemented left too many bugs and things that doesn't make sense. Let's see what we got there;
-. Not all the recipe works. You need to check one by one which ones are actually working and which ones don't. This is obviously bugs.
-. Not all the needed ingredients are available. Some you can get in infinite amount, some only by luck and some is nowhere to be found. For ex.; how in the hell we're going to get the likes of treant twigs when there's not even one treant to take it from ?
Demon spider leg is another example. You can only get this if you're lucky to find demon spiders in Samarach and is skilled enough to actually catch them before they disappeared. There is no second chance.
On the other hand, you can find tons of creature parts from traders and hunters, most of them aren't included in any recipe. Clearly these are oversights.
-. You can get essences of all kind, but there is no mortar and pestle anywhere to process them, no leather/iron ingot either. So you ended with lots of essences but no matrix to contain the enchantments.
-. Price for enchantment doesn't make sense. Say, you make a Ring of Fire Resistance, that costs about 9,000 gp. But you can also enchant a random ring with exactly the same enchantment for 3,000 gp. If you actually make such items, it's like you're cheating yourself.
-. Price for weapon enchantment is so prohibitively high at early levels when it was needed most. Yet after certain stage in the story, you get practically endless fund and matrixes for such enchantments, allowing you to make like, unlimited supplies of insane weapons. In OC, you might make at most 4-5 really powerful weapons, while in MotB, you might make perhaps 1-3 end-game level weapons. But in SoZ ? You can literally crash the artifact market of the whole Faerun.
