There's a good amount of adena/items you can still farm daily from the remaining level 9x content although it remains to be seen how much will be still available as upcoming patches will see them gradually being deleted. The strange thing is they provided a mechanism to fast track new characters to level 99+ so not many newbs will even know all this actually exist yet improved the rewards for all this "old content". Perhaps some of the following information might be of use to you/intermediates and anyone else strapped for cash and have time on their hands. All of the below should be done with a level 99 char max, from experience 95-97 is optimal.
Kimerian/Kimerian Epic instance (90+)
You can make a bunch of level 90+ characters very quickly (preferably melee DDs) and do this instance daily for each of them. You don't need any special gear, the standard Paulina stuff is all you need. To start either instance you need to speak to Naomi Kasheron in Ancient City Arcan but before that you need to farm the quest items from Pan Direm mobs @ the Fairy Settlement near the waterfall (ask around in game). Typical drops for defeating the boss are EWRs/EARs but you can get Twilight armors/Apocalypse weapons from Kimerian and Seraph/Specter for the Epic one if you're lucky.
Nornils Garden instance (93+, Spicula Zero raid boss)
This instance has been disabled temporarily because of a bug but the rewards have been improved to Eternal armors/Amaranthine weapons if you're lucky. You can also do this daily but you need at least 2 characters to enter. You need a decent DD for this instance but it doesn't really have to be super OP, it's similar to Kartia but much quicker. You can also farm BEARs/BEWRs from this instance.
Kartia instance - Guess this needs no further explanation.
Spezion instance (90+) - For the intermediates I guess but you need 5 for this (just to enter), then you can drop 3 characters and just use 2 for the stupid teleporter stage, and from then on 1 decent DD is enough for the actual raid. Rewards include Apocalypse/Twilight, Elcyum powder. This instance can be done every 4 hours.. knock yourself out lol.
Remaining level 9x raid bosses
Some of these bosses will probably be out of reach for most newbs but if you have one decent melee DD between level 95 to 99, you can do these bosses daily for a chance of getting Seraph armors/Specter weapons. They spawn randomly during the day but if you maintain a character between 96/97 you can look them up from the map directly to see if they are on. Generally these bosses are usually dead fairly quickly since they removed the grade requirement for weapons/armor so it's very easy to finish them off with a low level character and all the new OP gear we have in game.
"Easy" bosses (low HP)
Lv 97 Crook The Mad (Guillotine Fortress) - drops full Seraph/Specter items, EWR, EAR. Daily random spawn.
Lv 97 Hoopon The Warden Overseer (Guillotine Fortress) - drops full Seraph/Specter items, EWR, EAR. Daily random spawn.
Lv 96 Gigantic Golem (near Kamael Village) - drops full Eternal/Amaranthine items, EWR, EAR, BEAR, BEWR. Spawns every 12 hours.
The Gigantic Golem is probably a well kept secret since this new patch was introduced. This boss now drops 1 BEWR/BEAR + 1 EWR/EAR with 100% chance + other stuff/soul crystals/Amaranthine weapons (low chance). This boss spawns exactly every 12 hours from the last kill so it's never on most of the time being the last remaining predictable field raid. On Naia I see this boss being farmed by 2 characters.. sorry to burst the bubble ; ).
Medium/Hard-ish bosses (medium to lots of HP)
Lv 97 Guillotine of Death - drops full Seraph/Specter items, BEWR, BEAR, Ancient Dyes, soul crystals, etc. Spawns randomly between 1 to 2 days.
Lv 95 Spicula Negative - drops full Twilight/Apocalypse items, BEWR, BEAR, Ancient Dyes, soul crystals, etc. Spawns randomly between 2 to 4 days.
Lv 93 Garden Patrol Captain - drops full Immortal/Requiem items, BEWR, BEAR, Ancient Dyes, soul crystals, etc. Spawns randomly between 2 to 4 days.
There are also some Lv 90 bosses in Gracia like Torumba (bugged), Dopagen, Taklacan but I've never bothered with them since you can't jump to their location so you have to run all the way in from the entrance. You can look these up if you're interested but bear in mind much of the info regarding these bosses are being removed from the Wiki.
Good luck and happy farming before some or all of this are gone.
