Ultima Kill Needed (Can Pay)

Temenos West-

You don't have to kill every single mob, with an eva build and using delta thrust the mobs will only get off 1 tp move or not even. Don't need to fulltime eva gear but use it to get shadows up. I killed all of the beetles because they are aspirable, so magic hammer and go to town on them. You really only need to kill one mob for portal to open but you can kill a few on specific floors to get time chests. For the final floor, just sleepga them all + auroral drape and go to town on them. I was /nin and MP upkeep wasn't that hard tbh, you can sleep them so just rest if it gets bad enough. You can spell spam on the first two to get the numbers down to a more manageable level if they wake up.

Goblins are really easy, just sneak around the patrol ones and kill the stationary one.

Gigas floor, only kill the roaming MNK. I haven't tried the three in the middle but it could be done I suppose. Charm might suck so I would save that for last if you do attempt it, otherwise kill the MNK that runs around the circle and head up (flash or bind or sleep him during 2hr, eva gear).

Sahagin floor, had some trouble here once or twice. The mobs can link and they are pretty close when one is patrolling so keep that in mind.

Demons floor, two sets of black magesx2 kill them by pulling one group and sleeping it. The blms have little hp/def and drop really quick. I wouldn't recommend taking on the 3 in the center due to time/astral flow.

Antica floor, very easy just make sure you have echo drops lol I forgot one time but still made it through. Also make sure you have shadows up for the RNG because 2hr can be damaging.

Tonberry, stay away from the smns... When you go to fight the ninja make sure you pull it away from where it spawns because its 2hr sucks. It killed me at 10% HP left one time with 2hr, solo, so be careful. If you don't get portal from the stationary ninja's, then pull a THF and it should open. When portal opens, make sure you observe the movement of the smn tonberries if you never did this zone before. Don't aggro them or you might die or have a hard time going up.

Goblins, final floor which can be tough on MP. Make sure you buff up and then sleepga them and deal with the BLMs first. Auroral drape is a good idea so you can silence them. Keep in mind, every one of these mobs is aspirable so I set both of my aspirs for this floor.

This zone is really easy, you don't even fight avatars until final floor (possibly) unless you want items. The elementals take normal physical dmg so just melee them down and use sanguine blade for nice dmg/cure. Earth elementals can petrify you so be careful on that floor, and you have to fight two at once because they link no matter what. Eva build will really help if you get petrified. Dark elemental on the last floor can be a little annoying with sleepga and curse so make sure you are careful and set a light based sleep as well. Fenrir is extremely easy if he pops, I destroyed him w/o him even 2hring with like 3 spells.

Hope that helps somewhat if you try it.
