How to get 0 perpetuation avatars solo...

So, this post is more of a thought experiment more than anything, as it's currently not practical to accomplish this. So, anyway, on with the thought experiment.

The elemental avatars plus Diabolos have a -13 MP/tic perpetuation cost. I propose that it's possible now to get that perpetuation cost down to 0. It's not really practical now, nor is it easy, but it is possible to do this without any BRD, RDM, or COR or even a SCH. But it does require lots of endgame stuff as well as some high end gear.

Auto-Refresh - Auto refresh provides an automatic -1 to perpetuation cost regardless of avatar = -12

Nirvana - Nirvana has the most powerful -perpetuation cost weapon in the game, or anywhere for that matter, with a powerful -4 perpetuation cost. Good luck getting it though = -8

Summoner's Doublet - This Dynamis-Beaucidine piece allows -3 perpetuation cost on the avatar matching the day. For example, Titan will be -3 perpetuation cheaper on Earthday. Downside is that it only works for Earthday for Titan = -5

Nashira Gages - These hands drop from Proto-Ultima in Limbus. Proto-Ultima, unfortunately, is far from a pushover. -1 perpetuation cost = -4

Evoker's Spats +1 - The upgraded Artifact Armor feet requires drops from both parts of Limbus. -1 perpetuation cost = -3

Evoker's Ring - This is earned from a quest in Norg. This quest involves fight all six primes (again) plus Fenrir to get special items. All Summoners should have this item. -1 perpetuation cost = -2

Conjurer's Ring - This is a BCNM item that is, in my opinion, grossly undervalued. Downside is that the HP needs to be yellow, but with things like the sacrifice torque, sublimation, or zenith gear, it's not too difficult to do. -1 perpetuation cost = -1

Ballad - Now now, I can hear you saying right now, "But Keyln, this is supposed to be solo!", and I do mean solo. Even with the above gear alone, perpetuation cost is still at -1. But, if a Summoner uses the Bard as a subjob, the Summoner can sing Mage's Ballad to hit that 0 perpetuation. Granted, if there's already a Bard in the party, it would be better off using something else, like COR or SCH for the sub job. But this is a thought experiment. -1 perpetuation cost = 0

And there you have it. Getting 0 perpetuation cost solo using gear and abilities available right now. However, there are a few caveats for this to work.

1) Only avatars matching the day can be used.
2) Summoner must be at yellow HP (75%) at all times.
3) Bard subjob must be used.

Use this as you will.

On other news, I solo'ed Diabolos again this morning, and I got him under 15 minutes. I took screenshots this time around, so you can expect a guide very soon. Maybe as soon as tonight. Watch for more details.

Oh, and in SE news, there's an update in late July. If something exciting comes up, like new avatars, new frames, or something to make BST better, I'll post about it. ^^
