Liza's skill tree doesn't -quite- have everything, I used Emelia's skill tree instead a few times.
Like 10% of the time.
I basically never used Annie's though.
Anyway, I finished the SaGa Yattaf solo!
I also beat the EarthDragon!
This was a nice enough challenge, not very varied (because crowns make magic a liability here, see below) but short and challenging enough. Inferior to FFL1 and Romancing SaGa 3 solos. I'd really like to try Minstrel Song or Unlimited SaGa solo, but my laptop can't run a PS2 emulator and I don't have my PS2 anymore.
Strategy talk for the SaGa fans.
Shiva the Diva / Diva the Shiva just ate a few 19960 damage dream super combos.
Plus one doubleslash.
EarthDragon was a lot harder.
Against fully powered Uber-Yattaf (876 HP, Powered Suit, EMES tag, Budowear, Angel Broach) most of its attacks do pretty bad damage (double digit-ish) and can often be blocked. Its ultimate ball canon attack thing (I forgot the name) does 1 to 6 hits of 190 damage, but these attacks can be avoided (unlikely), deflected by a sword or blocked by a shield. I have a bunch of full healing items available, but using them means no deflecting attacks this round, which is very bad. The battle is very long as the bastard has 60 000 HP and is immune to DSC.
I had two strategies, with crown (offensive) and without crown (defensive), and neither worked until the very end of the game, but both came close!
With crown: I just tossed a bunch of useless attack moves on Yattaf just so she could get the weapon crown. In battle I used VictoryRune (Damage buff) from the Rune Sword (I bought this only for this battle), and then spammed Lifesprinkler and DoubleSlash (when I ran out of WPs). The problem is that I eventually had to heal, but was likely to be toasted if the dragon used BigIronBalls during the same round, because deflecting attacks is seriously important to survive against this.
Without crown: Same strategy but I equipped the VitalityRune magic, which gives pretty good regen per round. (170 HP) Yattaf was pretty much always at full HP for the Dragon's big bad attack, which is really nice. The big problem is that Deflecting costs 1 WP with this setup. So I had to conserve WP like mad, and use very basic attacks, which do pitiful damage and are easily blocked. I couldn't outslug the dragon in any way using any of these freaking 32 sword skills I had learnt.
I eventually won with the weapon crown strategy (so much for doing useless magic gift sidequests)
I noticed that EarthDragon never use SuperBallz two turns in a row, so I only ever healed immediately after getting hit by this attack, just so I was sure I could deflect anytime it used the super move.
This meant that I had to face the GiantBalls attack after getting hit by a few weaksauce attacks, with only 500-600 HP remaining at times. But with both a decent shield and a 0WP deflect, the RNG was clearly on my side. I only had to try that strategy twice to win with these stats.
