I am prone to undertaking tasks in-game for virtually no reason.
One of my recent objectives has been to hook as many keys as possible onto my /keyring.

Here's the current list. Looking for suggestions or keys I may have missed.
Trakanon Idol (Sebilis) is there, although I cropped it from view.

Missing Jaled Dar's Crypt Key(not sure if that was keyringable anyways, alot of people did the levitate and shrink method) I do not see the Earth B key. Don't see the Poinnovation factory key either(It's been awhile may have just been a flag). I had some key in pop called Odaen quest, not sure what it was, just showed up on keyring, think it had something to do with grummus. Missing Aerin Darr key as well. That is all offhand I remember.

Edit Now that I remember a few more, the Arx Key)never had it so, no clue if it was just a port to Seru or keyringable) for Seru. The Hole key. Missing Symbol of Torden for Aggies Tower. Pretty sure Samanna's site had a list of keys and ringable or not easily checklistable.

I'm at work now so cannot check my own key ring (I've always loved to collect keys and flags as well), but I do remember that key to Jaled Dar's lair wont go to keyring, always had to have the key with me.

I have the Odaen quest too, he's NPC in PoD but he never gave me any tasks or quests when I tried to find out what it was all about. I thiiiink it has something to do with the changes they made to PoP flaggings few years ago, but if you have already flagged to Eles or Time old fashionable way, nothing will happen if you talk with the npc. I might be completely wrong though!

Missing Tunare's Shrine Key.

I've got Jaled'Dars banked and it still won't keyring.

Passkey of the Twelve is the EarthB key (isn't it?)

I can open Innov Factory door, its just a character flag.

Aerin'Dar key is also banked, it still doesn't keyring.

Seru's Key is a right-click cast portal spell into the Arx Foris. I've got that item on my beastlord and it doesn't show on /keyring.

I added the Paineel and Hole keys today!

Symbol of Torden is banked as well. I'll have to drag some help along to make the ascent to Agnarr's area one of these days.

I'm not familiar with Odean. If its PoP backflagging then I'm probably unable to complete it since I took the full path to Time back in the day. Worth checking though.

Tunare's Shrine and Dreadspire Library added to the to-do list!

It doesn'tkeyring, but Icon of the Alter (allows you to request Ikkinz 4)

Ther are also the 3 Single group Ikkinz Trials (which don't keyring, but unlock those areas)

SoF - Key - Crystallos Raid? :)

wtf ~ I'm workin on it!

Don't you get something on your keyring once you defeat Meyong in Demi? Never could figure out what it was for though.

Yes u get a flag on key ring after defeating Mayong

Never mind lol half of what I listed, after further review were not keyringable, it has been awhile, lol. As for Odaen, I had no clue what is was just appeared one day out of the blue, never did alot of flags in order. But, I might make a suggestion though, for someone to lobby keys if they want to, try getting them to add airplane keys to key ring(that never went well), and also the marks from the justice trials, symbol of torden, Aerin darr's crystalline globe,and such to free up some bank slots.

I never did understand the change behind Plane of Sky keys.

Changed to permanent, but cannot be added to keyring, thus forcing me to permanently commit a satchel to storing the keys forever. I have them stored adjacent to another satchel filled with keys that likewise cannot be attached to the keyring.

I don't see the point in exempting any permanent/nodrop keys from the ring. Makes no sense to me.

There used to be a problem with corpses being all over sky for one. Especially, the way I did it. Lots of necros would key up and die there and have their corpses for convenience. Clerics as well. Then, the druids like me with cryptmaster conjuring stones(was very easy to manipulate the lore tags on corpses) res goo from dragons necropolis(until the nerfage, sucked didn't have a chance to recamp it before the nerf, not that I ever would have clicked it anyways) from dragons necropolis, until, I got a staff of forbidden rites(until the nerfage, after that it never got clicked).

I used to go up and sac myself regularly, being the dt magnet was usefull, naked with keys and stuff to bridge over with on my corpses, sometimes the patch corpse wipes would sting allittle. After the change there was no need of all the corpses, unless you wanted the bank space. Believe me, Thunder princess isle, for those wanting to go that route through sky was not a picnic to loot, and start up bridges and stuff on with 30 the 40 corpses just lying around.

I forgot about this, there is a list on Magelo of all keyringable things.

If its on my key ring I dont have to keep the key anymore right? Coming back after 5 year hiatus so some things are foggy lol

Right, although some people like me don't want to take any chances, and keep old keys and such anyway.

One thing that you should know is that apart from bugs, it is no longer possible to lose your gear due to corpse decay. Instead, any gear on a corpse that is 7 days old gets sent to Shadowrest, where you can retrieve it at any time. Some of us make extensive use of the "Bank of Shadowrest". :) After all, why not send old items there instead of deleting them?

There was a wizard in my guild who used shadowrest as banking space, then one day all corpes went puff and soe could or would not get them back for him

That is a risk that you take.

However, deleting an item is guaranteed to result in the loss of that item. By sending it to Shadowrest instead, there's still a good chance you can get it back.

Good to know, thanks.

So far I have a ton of bank space, but thats mostly due to not planning on doing tradeskills (too much time sink) this round probably so I have offloaded all tradeskill items I still have on to a mule.

Plus after 5 years there was a ton of quest pieces I could just dump due to better stuff available these days item wise so why bother finishing somethings that result in nodrop items I wont use. :)
