As someone who has consigned themselves to f2p limitations, I’ve traveled this road long and hard. As a reference to how much space I’m dealing with vs. you, I’ve got 8 chests and 6 chars with backpacks, and never a mule in my possession at any point in time, if that all helps.
So, that being said, I would get rid of your tops as you can on Realmeye or USW2 first of everything. The values of those fluctuate wildly, and are pretty situational for interest. Pots are ever so slightly more reliable because they are a universally needed item across characters.
That being said, next, I wouldn’t hold on to any of your mana as they are, on average, far less valuable than they used to be. Life is the only pot I’d store I’d you had to.
Now, this is where your opinion comes in, especially as I have to flit back and forth on this: What is more valuable to you, keeping the full value of your assets (aka life pots), or condensing them down into Glifes and entirely UBHP/DECA rings (As of now, UBHP is probably more efficient if the two, but sometimes you’ll strike it lucky)? With my limited inventory space, my usual choice is condensing down to the rings and reverse breaking it down when I need the life to consume or buy items (like those tops)/pots.
As for the rest of the junk, I have a single chest for the dyes/cloths, and an trying to whittle that down to almost nothing in favor of both what I have in my gift chests and that we can now purchase that stuff with fame (), a couple of the vanity items I love are stashed on one of my inactive characters (like my 2017 token and Energy Signet).
Most of what I have in my vault are ST/UT items and marks. The marks I hoard on my characters as well, even the ones that I use more often, swapping them off of my immediately active character. As a final purge of items, I only bother storing the epic and end game marks. I’ll normally just run the current scout mission, and the lowest two ranking chests aren’t usually worth the effort, imo.
And finally, after all that jabbering your ear off, there’s one more bonus note: if you do choose, if you’d like to store other pots so you don’t have to do as much merching of your rings back to smaller items/pots, you can always do the relatable quests at the tinkerer to meld 3 pots into a greater pot! Yes, you lose a pot of value, but because it’s sent to your gift chests, pronto! You’ve created free vault space at the cost of an extra pot!
Sorry for the ramble. Hope this helps! If you have any questions or insights, please tell me. These are just some methods that work for my personal account, and not necessarily the best way!
