Create The Ultimate Currency Sink

Something that lets you turn any orb into a random orb. The higher the orb rarity, the better the odds of the orb being a rarer one. For example, an exalted orb is more likely to turn into a mirror than a transmutation orb, but both of them can still become a mirror. However they're both probably just going to turn into a scroll of wisdom instead.

Some one mentioned a Iron Golem from D2. Don't give it your passives, but instead give it all stats and sockets (including the gems and supports included)

Really want mercenaries, have them like exiles equitable and bearable and focus around using the more awkward items that don't see attention due to cookie cutter builds, even if I can only roll with my boys single player I really want something more than just levelling for my main who I feel is near bis

But yeah staff orientated merc, non lions eye bow merc, 1h mace merc... Basically make more items more desirable crafting IMO

I think I thought of the best one this morning! Why not pit the ego of one against himself?

Players are able to buy titles that show up in chat, by their names in the mouseover, and in listings for currency. Purely cosmetic of course.

Let's say you can pay 10 chaos for the lowest up to a mirror for the highest. There would of course be tiers between exalt and mirror ranks (5 exalt, 10 eternal, etc.). Imagine how many people wouldn't be able to resist spending an exalted orb on something like that?

A stack of Mirrors vendors into an item that has a 10% chance to give an extra socket. If it fails the item is destroyed.

Spend 10 chaos to 'copy' an item (makes the original unusable) that lasts for maybe a week? So you can lend things to other. Once the timer ends, the original becomes usable again and the copy disappears.

Spend X Fusing(?) + Y Chrom for an Orb of Precise Chromatism which rerolls the colour of sockets without gems in them -- meaning you could reroll specific sockets. Now you can get that GGGRRB pure ES chest you wanted !!

Vendor a gem + some ammount of currency (GCP?) to get a no quality high level gem, depending on ammount of currency.

Spend Lotsa Currency for some (but not all) microtransaction-only items (or just different colours than what's offered in the shop). Not my favourite idea but it would certainly remove currency from the economy.

Spend 100000 exalts to bribe a bandit into giving you his reward on top of other non-bribed bandit's reward? as you can tell I'm running out of ideas.

Shameless D2 bump but sell GCPs to spawn Super Kole who can drop a unique item. :P

-Add npc to the game that creates guilds for orbs
-Increase max member slots by spending orbs
-Shared guild stash that increases its space by spending orbs
-Guild master must spend orbs to promote members to different roles
-Options like view online guild members/seperate guild chat by paying orbs/week
-Guild duels with top 3 of each guild. Duels among each guild to specify beforementioned 3. Register with orbs. Run every week and 1st guild gets items like the new demigodswhatsitsname.

We could expand the map system into the lower levels. With a twist.

From, let's say act1 merciless (or lvl50, or whatever works better), the magic vendor sells 'twisted'/'lesser'/'mimblewimble' maps of the main zones you have already visited/have waypoint.

These 'twisted' maps do not go into the eternal lab. Instead you use it in the town and it open a portal to the 'twisted' zone. The white 'twisted' zone is exactly the same as the main zone, so a white one is useless.
The thing is that you can add map mods to it (from a reduced affix pool, take map layout modifiers out, for example, to ease the design and to reserve things for the real map system).
And instead of giving IIQ%, the mods would give extra experience.

The idea is faster leveling paying currency.

Example:
You buy a 'twisted' Fellshrine for 1 alch (just saying). You transmute and alter it and end up with a couple of manageable mods for +20% extra exp. Now you do a somewhat harder fellshrine run with +20% exp, for which you have paid 1 alch, 1 transm and 1 alt.

Possible modifications:
-Once you enter the portal, the portal is closed. Town portals can take you out but not inside again. Your party mates are rejected from entry. You have to do it solo and do whatever in one run.


Reasoning:
-Levels 50-66 are 'mid-game'. The valley of suck that spans between early game (where everything is new and cool) and the everpraised endgame. This suggestion reduces slightly the length of that valley and introduces something 'new' to do there.
-While also introducing a sink to the lower currencies.

I don't condone this idea, I haven't put enough thought behind it.

Perhaps turning currency items in to an NPC for some temporary bonus. A minor boost to experience, quantity, rarity, or damage - that expires after a short period of time.
