didn't know untill yesterday that you were even close to comming out with a crafting plan. i've beening thinking for a while now that it would be great to have a barter/crafting system in place that would let a player trade in collectables, gems, ingredients from all over the game to create new items mostly potions and consumable clickies and consumable weapons (such as thrown weapons and arrows).
House P can have one in thier potion shop and you could craft improved potions of haste, invisibility, jump, extra spell damage potions, even use the exp. pots given as house D rewards as components to created more powerfull potions.
House J would have one as well enabling the crafting of Health and even Mana pots as well as potions of divine spells.
Gems could finaly be used as an added ingredent to come out with a way to make a consumable clicky item that can be used on an ally as well as ones own self and various attack spells at various levels, kinda like crafting your own holiday cookies-which of course could be used as ingredients. or creating a trinket that offers a bonus to skills, element resistance, ac, run speed. or forge a custom trinket of say water breathing and swim skill, or jump and featherfall and so on. some formulas can be simple for low level bounses some can have component requierments of say shroud / IQ / or more and of course you have to have the right kind of gem which drop oh so randomly.
Soul Gems could be crunched in stacks of 10 or more you know something to recieve a one time use summon of the thing whos soul was trap'd.
could use those festival twigs with other items to create wands at various levels-not recharging of course
have the collectors have a barter box up for the items they collect for ex.. 3 sweet white caps can get you a small heal or repair pot, and you get to pick. just so the reward isn't so random or useless youll know what your getting and they can give items for combinations of thier desired collectables in various quantities
Plain consumable weapon items such as arrows, throwing knives/axes so on can have an element or effect placed on them..they still get consumed but you can make them fire, slow burst, poisoning, giant bane, and extreme formulas for slayer items.
Over all the players would be able to take those items that have either lost value or have had no previous perpose and give them one...the items still need to be found or bought or forged to get your items...and of course make them bound either to character or account.
