Rare summon scrolls for those gold collecting pets

Here are a collection of virtual items that could have low drop rates, forcing them to be sold on the Real Money Auction House:

    * Items or Scrolls that magically increased your Stash, Shared Stash, and Bag Space slots. For example, cheap diablo 3 items a "Scroll of Minor Bag Space" that increases your slots by 3.
    * Rare summon scrolls for those gold collecting pets.
    * Even more rare summoning scrolls that summon pets that gain +10% gold. Just like the Daeity pet. (Blizzard, hint hint.)
    * Vendor potions that increase your selling or buying prices for a fixed time or fixed number of items.
    * Salvaging potions that improve salvage results for a fixed time or fixed number of items. Same for better enchants, gems, etc.
    * Remove Experience Shrines, and instead have rare "+15% XP Gain" potions.
    * Rare potions of Magic Find and Gold Find that complement your gear. These would be time based spells (e.g. 30 minutes.)
    * Collecting multiple rare potions that can be mixed together to create new and improved effects.
    * A portal scroll (like in Torchlight) where the player is transported to a small zone with above average loot and/or a guaranteed rare spawn. Because players might be paying $1-5 for something like this, buy diablo 3 gold  muSvsE40  it's sort of their version of DLC since it's an area inaccessible to most players unless they purchase it.
    * The return of the Nephalem Cube and the Cauldron of Jordan, except that they're rare drops, they're tiered, and they require rare "upgrades". For example, you can only break down level 10 items when you get the initial item. You purchase pieces or upgrades to the item on the RMAH, and then you can break down up-to level 20 items, etc. wow gear Sort of like a cash sink vs gold sink.
    * Mailbox upgrade items. Several items that allow you to upgrade your personal mailbox and it's appearance. Allows you to send more items at once and lowers postage fees. http://www.tasidan.com.cn/bbs/boke.asp?f7gi.showtopic.54909.html
