Same. I ended up going back to my other 6-hour-old save. I found a good place to run around now though - when you have the strength, just take down the Adamantortoise on Pulse without using Death or Summons - save the Summons for the Adamantoise. I'm going...

Save point --> Adamtortoise --> 3x Adamenchilde --> Adamantortoise (with 3 lionthings) --> Adamenchilde (when you exit the area there should be one, after this you should have almost 4 TP) --> the Adamantoise to your left (Summon/Death) --> Take on a few goblins/lionthings/etc. on the way to the Adamantoise at the other end so you have 3 TP --> Adamantoise (Summon/Death) --> Save point, save, go to menu, load, start from the beginning!

This is making me very, very quick money. It works great with Vanille/Fang/Hope, with Fang as leader for the Adamantortoises and Vanille as leader for the Adamantoise. With Fang using her maxed out weapon, I can take down an Adamantortoise in three minutes without Summons or Death. Vanille rarely fails with her Death on the Adamantoise, so it's faster to just use her than to take it down through other means. The 4-5 Adamenchilde you'll kill along this route also give you some nifty Gold Dust. After the first Adamantoise I usually have 2.5 TP or so, so just walk towards the other Adamantoise hitting anything along the way, and end up with 3 TP for the next one that way.

My strategies for both...
Adamantortoise: Fang/Vanille/Hope
SAB/SAB/SYN - I like to take a few shots at Deprotect etc. on the legs while Haste gets put on by Hope.
COM/MED/SYN - Until Haste, Protect and Shell are on.
COM/MED/RAV - Continue attacking legs with this.
COM/MED/MED - For about two seconds after each Quake attack.
COM/RAV/RAV - After the next 'stomp' attack following the Quake attack, I switch to this as I know another Quake never comes that soon afterwards, so I can take the time while on full green health to decimate the legs. Whenever the stagger is around 500% and the legs are half-gone (should only take one stagger each with COM/MED/RAV let alone COM/RAV/RAV) you should hit in with Highwind. Bye bye leg.
SAB/SAB/SYN - Once both legs are down, switch to this and get Deprotect, Deshell, Imperil, Slow and sometimes Curse on him. Vanille + Fang working together shouldn't take too long, and it allows Hope to put on some potentially important offensive buffs before switching to...
COM/RAV/RAV - 'til death. Once it's around 940% or more, hit in with Highwind for the finishing move.

Adamantoise: Vanille/Fang/Hope - Well, if you don't know the Death strategy, let me know. It's what I use.

Accessories: Vanille has an Earth resistance accessory (currently 40%, although 15% was still working fine before I upgraded) and a magic boosting accessory (+150) alongside the two accessories which help you with items/rare items, Hope has 2x Earth Resistance accessories, a health bonus (a tidy 1,400 or so) accessory and... I forget his other one! Fang has a fully leveled Power Glove, the Genji Glove and two items which allow to her have Random: Instant Stagger, which is awesomely useful.
